You want a set of warm colors and a set of cold color primaries..This combination is good for short cutting color mixing..Brand's don't really matter, understanding the color and why your using it is..Color is generally used in 2 diff ways, to faithfully represent what you see in front of you or to utilise to invoke feeling or emotion..The difference between a cold color and a warm one..EG Your Lemon yellow would be a cool yellow, you ocre more a warm yellow. having both imho really helps mixing your correct secondaries or tertiary s..EG Try mixing a say a bright green with a warm blue and a warm yellow..It will float more to a olive color than a bright green..using the two cold colors will mix a brighter secondary so on..Color theory though is less about the color wheel although critical to know it or faithfully representing a color..its more about understanding why to even use that color or how a color beside it may affect it..How shadows affect color etc etc..Why cool colors tend to recede and warm colors advance, how you can use that to advantage or how you can completely change just one color in a ref to invoke a completely different emotional feeling to the piece..I use a brand out of Aus called TOP for a lot of my canvas work..Their range comes with this understanding, they dont sell 300 different colors, just warm and cold primary sets..Buy a set of trans Warm, a set of trans cool (Six in total) 3 warm, 3 cool and then buy a big bottle of white and black..With those 8 paints bottles, any color both opaque and transparent is possible besides your neons, metallic's and the like..The other bonus is it sprays beautifully with very little tip dry and you get a decent volume of paint in comparrison to other brands for the same price..I only use that brand though for canvas work, I have a different brand I prefer for auto or any solid base style work..There are though many other good brands for canvas work. Good luck
