    Mixing watercolour paints |

  From bob: So, I'm making a chart to help me mix watercolor paints.  There are 
25 different paints. Each paint will mix with another paint just 1 time.  
There is no need to mix red with blue, and then blue with red. Since 
the result is the same, we only need 1 combination of the 2 paints.
And there is no need to mix red with red, so we can eliminate 25 
combinations of the same paint. Answered by Penny Nom. |
