If you really want a near perfect match, reverse paint in yellow AND blue. Start with the color that is most transparent. Using a matchnig color, carefully paint the walls of the drilled hole approximately in the area where that color occurs. Let it dry overnight. Then paint the entire inside of the hole the the other color.
I use a Q-tip for painting, pull off up to half of the cotton to get finer details in painting. The same approach works well to put color in any nearly transparent blank. On a whitish nearly transparent blank try putting on a random swirl of a color like blue. Then come back the next day and paint the entire inside with green. It makes for great depth of color.
