removed noise, fixed formatting & typos etc; also, transparency is not "gray-scale" since it's not a color, added modality to RGB being "the" digital color space etc

| Jul 18, 2014 at 16:54 | comment | added | ashes999 | @Nolonar feel free to add your own answer and explanation, since you know about CMYK (I don't know enough to add it to mine) | |
| Jul 18, 2014 at 16:15 | comment | added | jcora | Yes, also subtractive systems, although I haven't actually seen those in game libraries. | |
| Jul 18, 2014 at 16:12 | comment | added | Nolonar | About the other color systems @jco mentioned, there would be CMY, which is very similar to RGB, and also HSV/HSL. I'd at least mention the HSV or HSL system, since the channels they use are significantly different from RGB. As it stands now, people might think a channel is a color; in HSV/HSL it is not the case. | |

| Jul 17, 2014 at 21:02 | comment | added | ashes999 | I chose this picture because it's illustrative. The OP seems confused about the concept. Explaining the concept more simply seemed more important than finding an exact image. Technically, it should be four grey-scale layers (which is what my initial image was), but that's more confusing. | |
| Jul 17, 2014 at 20:46 | comment | added | Slipp D. Thompson | @Alex It looks pigment-based to me. Absence of a color would be white, presence colored, and heavy presence darkened. | |
| Jul 17, 2014 at 20:45 | comment | added | Alex | @SlippD.Thompson is right. In RGB, white is made by having each color channel have full intensity, meaning that ashes999's image is a bit loose with the rules. | |
| Jul 17, 2014 at 20:20 | comment | added | Slipp D. Thompson | Shouldn't those per-channel images have values from zero-value (black) to full-value (e.g. red) instead of black->red->white (e.g.) as shown? (Something like this: f.cl.ly/items/2Q2C1z2s331f1T1U341G/images.png ) | |
| Jul 17, 2014 at 19:20 | comment | added | ashes999 | @jco I'm not sure which other ones you mean. And I'm not sure if they're relevant to the discussion about "channels." | |
| Jul 17, 2014 at 18:27 | comment | added | jcora | You might also want to mention other color systems, because the additive one is not the only one used | |
