RGBA and RGBAW Color Mixer

I've used RGB and CMYK color mixers found online or in Photoshop. I'm wondering if RGBA/RGBAW ones exist especially that LED fixtures incorporate these colors nowadays.

I don't quite understand your question.

I can say that the primary colors of light are red, green, and blue, as they are additive colors, meaning you combine them to create colors. In Art for example, your primary colors are red, blue, and yellow, also know as the subtractive colors, as they adsorb light and only reflect some of it back.

Mixing light is an additive process; mixing paint is a subtractive process.

Technically, the primary pigments are CMYK.

No, your RGB color mixer in Photoshop is not because of RGB light fixtures. It's because your Computer Screen and TV use RGB pixels to display images and color. Ever look at a monitor really close? You can actually see the pixels.

P.S. The physics of light and light theory are very interesting.

An example of RGB Pixels, try zooming out then back in:

Thanks Synaxis. I'm trying to find out if there's a tool that will tell me that Deep Purple is
RGBA:
R50 G0 B105 A50
RGBAW:
R50 G0 B105 A50 W10

Right now, I use an RGB mixer then eyeball the Amber and White
