https://stash.reaper.fm/38676/amagal...rs%20v2.00.gif

# Adjusts the colors of ANY theme in groups

- Theme supports both zipped and unzipped themes
- Offers Brightness, Contrast and Gamma adjustments
- A/B Button to toggle between the current setting and the original theme colors
- Use the Take Snapshot button to store settings and make new adjustments on these rather than the original theme's colors
- The Snapshots are the base colors on which you make adjustments using the sliders
- The adjustments are applied to the selected color groups in the Color Groups Tab. The rest of the theme colors are copied over
- In the Color Groups Tab you can inspect or change the theme colors on which the adjustments apply
- In the Listbox you can choose (click) or delete (Alt-click) your saved Snapshots
- If you change the Color Groups selection a Snapshot is automatically taken
- UNDO/REDO buttons to undo/redo adjustments made on the selected theme color Snapshot in the Listbox
- User is prompted to save when exiting and if there were color changes in comparison to the original theme
- If user changes theme while the script is running, script automatically closes and prompts user to save if there were any changes
- The new saved adjusted theme inherits the old theme's "Default_6.0 theme adjuster" settings, if any
- Script Requires Lokasenna GUI v2 and JS_ReaScriptAPI to work. Both are checked if they exist at the start of the script

available in ReaPack!

https://stash.reaper.fm/38520/Adjust...e%20colors.gif

I am making a script that adjusts the colors of any theme. To finish it, I need the formula for colors that can be blended:

https://stash.reaper.fm/38521/theme%20blend.jpg

Does anyone know this? How can I go from a number to r,g,b,a and blend mode? Furthemore, how can I calculate the visible color of two blended colors? (for example grid lines, over arrange background color)

Thanks!

_Stevie_ · 03-10-2020, 05:49 PM

Woah, what a great script, thanks!

X-Raym · 03-10-2020, 06:55 PM

Very promising !

Blend mode are quite standard operation, with Alpha as final multiplicator.

Look at formulas there for eg : https://photoblogstop.com/photoshop/...odes-explained

Vagelis · 03-10-2020, 07:28 PM

Very nice

nofish · 03-10-2020, 07:44 PM

Cool!

I'm thinking if the changes were applied immediately when moving the sliders (and have a Revert button instead) may be even nicer.

Nostrap · 03-10-2020, 08:24 PM

Excited about this!

amagalma · 03-11-2020, 04:08 AM

Thanks guys!

Thanks for the link! The blend modes that are available in Reaper are: Normal, Add, Overlay, Multiply, Dodge and HSV adjust. The formulas may be of help to determine the resulting color, although the start of the article is a little bit discouraging ("Working with blend modes is almost always an experimental process. Because it’s nearly impossible to predict the results")

Still, we need a formula that translates the integer of a color to its components. For normal colors there are:

Code:

r, g, b = reaper.ColorFromNative( col )
col = reaper.ColorToNative( r, g, b )

But for example, let's take the color of the Play cursor.

Code:

playcursor_color = 0 (white - r,g,b = 256,256,256)
playcursor_drawmode = 131072 (normal 1.00)

If I change the fill mode to Normal 0.5 then the values are:

Code:

playcursor_color = 255
playcursor_drawmode = 196608

We need the formula that will translate the integer of the drawmode to the mode and value and then the formula that relates this blend to the affected color (in this case playcursor_color).

And then we need the maths (your link may help) that will relate these values to the values of the base color so that we know the resulting visible color.

That is what I wanted to do, but I don't think it will work, because loading a theme is not immediate - not fast enough. The way it works is by making a copy of the theme and writing the changed values to the copy (the original theme is left untouched), then loading the adjusted theme when one hits apply. I can certainly add an undo (and redo) button, though, that will revert to the previous values and previous adjusted state.

Great job!

Oh I wasn't aware the script is that involved, makes sense.
Thanks.

Oh don't worry, this is from a creative graphical manipulation/illustration context (aka, when you are making a digital paiting or a digital photo manipulation), in the math field there is no randomness involved :P

This looks like you have to do some reverse engineering as it is reaper specific. Set normal to 0, normal to 1, Add to 0, Add to etc... You may find the formulas from the reslting data

This is super cool! Thanks!

todoublez · 03-11-2020, 01:12 PM

Wow this is a very handy feature..
Lookin forward to this !

pepe44 · 03-11-2020, 02:19 PM

That's a smart move towards a next great feature. Thanks.

amagalma · 03-11-2020, 03:12 PM

Script is on ReaPack

PhelixK · 03-12-2020, 09:55 AM

super nice feature here!
I just ran the ‘atc’-script and successfully managed to adjust the backgrounds/save as new. I understand this does not work on gfx elements. This was on Win10 r1909

Also tried on macOS10.14.6, and got the following error:
amagalma_Adjust theme colors.lua:137: attempt to concatenate a nil value (upvalue 'path')

Is there something I should do to make it work on mac?

.

Reflected · 03-12-2020, 10:48 AM

couldn't see this script on reapack

edit: found it after sync.

Shit! I forgot Mac and Linux use different path system.. I' ll fix this!

I have just uploaded the new improved version of the script (v1.2). I'll fix the Mac/Linux thing and upload v1.21 later.

amagalma · 03-12-2020, 03:01 PM

New version up in Reapack in a few moments.

changelog v1.25
Fixed order of appearance of previous settings to coincide with sliders' order
Fixed adjusted theme not saving if saved under the name of an existing theme file
Fixed OSX and Linux crashing

Reflected · 03-12-2020, 03:17 PM

BTW
is it possible to make a script which copy selected colors from 1 theme to another ?

It could be done but the most difficult part would be the color selection.. There are about 350 colors in a theme.. How would one select what gets copied?

martmix · 03-13-2020, 01:42 AM

is there a video that explain the steps i need to do,cuz
i dont understand nothing at all....

No, because it is very easy.

1) Do you know how to load scripts?
2) Have you got ReaPack?
3) Do you know how to extract the ReaperTheme from a ReaperThemeZip?

Which part confuses you?

Hi, perfect! -works fine on mac now.

A question regarding extended features in v6,
When using the color script on themes that are compatible with the Theme Adjuster in v6, I notice the script instantly resets all TA settings to default by creating a temporary entry called [adjusted__. This is of course to be expected due to the presence of a new theme file in the reaper-themeconfig.ini.

Then, when we decide to save as a new theme, I wonder if it would be possible for the script to automatically duplicate all those original Theme Adjuster settings and put under the correct new theme inside the INI ?
If not an option, I believe it's fine to do it manually.

with ticking boxes ? :P

some colors of other themes are so nice on eyes but too much work to copy one by one color

I could do that

Tagirijus · 03-14-2020, 09:44 AM

Thank you so much for this script. Worked like a charm on my modified "Concerto" theme!

Thonex · 03-17-2020, 10:26 AM

Wow... just wow!

pepe44 · 03-19-2020, 04:21 AM

For some reason i have this error. Just installed from reapack.

Hmm.. This points to Lokasenna's GUI library.. Could you run the action "Set Lokasenna_GUI v2 library path.lua" and then try my script again? Thanks!

Hi, I updated the script from v1.25 to 1.40.
Only checked on macOS, haven't checked Win.
Maybe you forgot to make the corrections for mac and Linux as well?

1)
Here on mac it doesn't work on zip'ed themes.. tried on Def.6 and another.
Got the following error:
Failed to extract ReaperThemeZip file. Make sure you have 'unzip' installed.

On mac, I assume the call for 'unzip' would be 'Archive Utility'(?)

2)
Tried using the script on an unpacked theme.
When saving, I get the following error:
... m Scripts / Various / amagalma_Adjust theme colors_v1.40.lua: 381: attempting to index a null value (update 'ReaperThemeName')

- the new theme is still saved or overwritten if using the same name.
- and the new theme loads with the correct color adjustments

- But, the Theme Adjuster settings are lost, whether it is standard or a custom version of TA.

In reaper-themeconfig.ini, only this single entry is created:
[Adjusted__xyz-theme-name]
param22 = 100

.

amagalma · 03-21-2020, 12:55 PM

Thanks for the report!

I'll check again about 1) .. About 2), it happens the same in windows, I'll fix it in a moment and upload 1.41.. The first is going to take more time because I don't have OSX or Linux to test

creator31 · 03-22-2020, 01:50 PM

Hi amagalma,

I'm curious to try this script, but it's throwing this error for me:

Quote:

JS_ReaScriptAPI not installed

You have to install JS_ReaScriptAPI for this script to work. Would you like to open the relative web page in your browser?

I've got reaper_js_ReaScriptAPI32.dylib installed in the UserPlugins folder.

I'm not expecting my old 32bit system to be supported, but if it did happen to be an easy fix...

Whatever though, thanks for your script. :-)

Are you sure the JS_ReaScriptAPI is correctly installed?
