I had learned that the difference between the red/blue/green primary color system and the red/blue/yellow system were due to how we observed them. The red/blue/green primaries are because we are looking at source light. The red/blue/yellow primaries are because we are looking at reflected light.
nuu. red yellow and blue. green is made by combining blue and yellow. RBG (red blue green) is a color system used on computers to define digital color(along with CYMK, or cyan, yellow, magenta, and key (or black) which is used for printing), but the traditional color primaries are RBY. the reason there's more than one system is that there are two different ways of combining colors: additive and subtractive. printers use subtractive color methods and traditional paints use additive... so depending on which you're using, the color wheel changes.
This seems to contain everything I would ever need to know about colors to start painting. Thanks for sharing!
One more thing... (hope the question is not too noobish. xD but i'm clueless about colors) before I even start choosing colors for my objects, the first thing I have to have in mind is my atmosphere right? And then choose colors according to any rule(triad, split complementary etc) based on that chosen atmospheric color as the main dominant color?
generally yes - the aim is to use the atmosphere to give your pic an "overall color scheme/look"- you want your color scheme to be cohesive - where it all looks like it's connected and part of the same picture.... when you don't factor in atmosphere or set a overall theme color, it can look really cartoony and fake. examples:
skill/subject matter aside, the cohesive color schemed picture is more visually attractive than the one where the colors are just all over the place. It's easiest to choose your atmosphere as a main color for your picture because it will encompass the entire picture... secondary colors or complimentary would be in the figure or focus area of your image.. and then you'd use a contrasting color to make details within the focus area/figure stand out.
