I could've sworn I asked this before, but I can't find it in my bookmarks or my previous posts for the life of me...
Anyways, how would I code the bars for like hair or clothing colour in dress up games? So that instead of having eyes and hair in multiple colours I can just have one, then use the im.matrix.hue to shift the colour with a slider bar that looks like this:

Or use sliders to adjust transparency or change a colour's saturation or something.

I'd like to know that too!

Never tried it, but the thread you're looking for is probably this one.

I don't think that it is what he needs.

This is tricky... there are many approaches:

1) No bar, instead (simplest way I think, but not (exactly, it will do the same thing differently) what you asked):

A number of image buttons with basic "default" colors.
Three bars with values from 0 to 255 for default color channels if someone wants a more unique color.

We did this as a practice couple of years ago, code is prolly lost to time but it sure as hell worked, this wasn't too hard to code just with the stuff from documentation. You will just assign the hair with correct color to some variable and it's all good.

2) Bar like your where you map colors manually through a dict, bit messy and a lot of work but it should be doable.

3) Writing a UDD/class/func that will map any image pixel by pixel to their values, get input coordinates from the mouse and return the proper value. It's possibly the best but also the most difficult way unless you've messed with this stuff before. If you decide to take this path, search latest posts by Molechan, I recall him messing with analyzing images and mapping them to colors pixel by pixel, I helped him with the loop a bit. That will get you started but the idea was to replace one color with another, not pick one from an image (there isn't much difference, you can get mouse input from renpy.get_mouse_pos or renpy.Displayable.event()).

I found the prototypes I came up with two years back (before I knew anything about anything in Ren'Py):

Some notes:

- I don't know if this is still working, it is really old, code was posted at a different forum together with images, I've deleted it long time ago from my Ren'Py SDK.
- You can obviously tweak/use it as you please.

*There is also a very advanced variant of the same but it will take hours to figure out, I can PM it to you if you want but code is not mine and it's a very, very difficult (and now dead) project to figure out .
