The person who taught me how to mix colours was my grandma. We used to paint together and we still sometimes do when I visit her ;) That is why when I started decorating cakes, mixing colours was quite easy for me... In this tutorial I'll try to explain all there is to explain. You'll see that mixing colours can actually be FUN!

Look how many colours and shades of blue you can get by mixing sky blue with other colours! :) I always make my greens from sky blue and yellow. If I want the green to be more bright/fluorescent, I add lemon yellow. If I want it to be more warm, I add golden yellow.
Look at the balls placed in the middle of the second row from the bottom (BROWN) ... can you see the brown showing in those blues? If not... compare those colours with the other balls placed in the same row. Look again at those middle balls with added brown... do you see the brown in them now?
Look at the last, bottom row (BLACK) ...do you see black touches in those balls? Look at each ball from that row starting from the left and going to the right... when do you start seeing the black touches?
If you want to practice, you can make a few blue balls of sugarpaste and add different colours to them... Add the colours gradually and observe how the colour changes.
