Yellow and blue make green right...so...

How come when you use blue ink on a yellow pad it doesn't become green?

The colours doesn't mix. The blue just goes over the yellow.

color mixtures are explained by additive http://en.wikipedia.org/wiki/Additive_color and subtractive http://en.wikipedia.org/wiki/Subtractive_color color.

I don't know what you're doing wrong, but yellow and blue light should make white light, and blue and yellow ink should make green

The amount of ink, coupled with the hue and shade, overwhelms the yellow. Pour some of the ink on the paper. Use a wet paper towel and smear it across the page. In the thinner areas it will be greener.

Its because the blue ink doesn't mix with the paper. It simply adds a thin layer of blue over the top.

Try mixing paint. If you mix yellow and blue paint together (as a liquid) you will get green. However, if you paint a layer of yellow and let it dry, then paint the wall blue and it will be blue.

It doesn't matter if the colors mix or not. If you hold a blue glas thingie over a yellow one, and you look at them from above, they will seem to be green.

As said above, the ink is simply to overhelming. Lesser ink (thiner), and it should seem to be green.
