General Question Graphics question: Color description

[llarian]

I recently ran into a situation that puzzled me. When working in sRGB colors are expressed in three characters such as 0,0,255. I ran into a four character description such as 0,0,0,255. I didn't recognize this. Is this a CMYK description? Could someone please educate me on this one.

Thanks in advance

Is Alpha first or last in the order?

Hmm, that you need to figure out... depending on the byte order it could be argb, rgba, bgra, abgr

I saw RGBA in documentation (regarding materials of a mesh).
