Ability to mix multiple colors in different proportions, not just 2 colors

[rider85]

it would be awesome if I could play around with mixing multiple (2+) colors.
In fact I will try to implement it in the active project as soon as several colors are available.

Here are a few examples of implementation:

1. Chroma-js: https://gka.github.io/chroma.js/#chroma-average
2. Mixbox:

//   MULTI-COLOR MIXING
//
//      var z1 = mixbox.rgbToLatent(rgb1);
//      var z2 = mixbox.rgbToLatent(rgb2);
//      var z3 = mixbox.rgbToLatent(rgb3);
//
//      var zMix = new Array(mixbox.LATENT_SIZE);
//
//      for (var i = 0; i < zMix.length; i++) { // mix:
//          zMix[i] = (0.3*z1[i] +       // 30% of rgb1
//                     0.6*z2[i] +       // 60% of rgb2
//                     0.1*z3[i]);       // 10% of rgb3
//      }
//
//      var rgbMix = mixbox.latentToRgb(zMix);

When I find the time I will look in to this

Hi, there, I have the same need: I need to translate this kind of thing:

mixbox_latent finalLat = 0.2 * latUp + 0.3 * latDown + 0.4 * latLeft + 0.1 * latRight;

The context would be

		vec3 up = ...
		vec3 down = ...
		vec3 left = ...
		vec3 right =...
		
		mixbox_latent latUp = mixbox_rgb_toLatent(up);
		mixbox_latent latDown = mixbox_rgb_toLatent(down);
		mixbox_latent latLeft = mixbox_rgb_toLatent(left);
		mixbox_latent latRight  = mixbox_rgb_toLatent(right);
		
                    mixbox_latent finalLat =  0.2  * latUp + 0.3  * latDown + 0.4  * latLeft + 0.1  * latRight;

                    vec3 colBg = mixbox_latent_to_rgb(finalLat);

Thanks!

It’s coming, I have this in my dev version.
No ETA though as I’m working on some other features before 3.0 will be released.
