It must first be ascertained whether we are trying to achieve red ink or red light. If light then red is primary. If ink then red is a mix of yellow and magenta and therefore a secondary color.
red, yellow and blue are primary colours, if you mix them together you will get some of the secondary colours, then mix the secondary colours with secondary colours and so on...
Red is a primary color, meaning you can't get it by mixing other colors, you can only mix red to get other colors.There are three primary colours that can't be produced by mixing any other colours. The three primary colours are Red, Blue and Yellow.
To get orange, you can mix red and yellow together. Adjust the ratio of red to yellow depending on the shade of orange you are aiming for.
You can mix red and blue to make purple. Adjust the ratio of each color to achieve your desired shade of purple.
To make gold, mix yellow and a small amount of red or orange together. Adjust the ratio of yellow to red or orange to achieve the shade of gold you desire.
