What other colors can be made with 2 extra cans of mixed paint?

[harnish@hfx.eastlink.ca]

I have two extra cans of Debbie Travis paint, color is Chai Latte CM29L
(a tan/sand color) and the formula off the paint can is:

Gallon - Base 85300 white
(Incand) - BLK 27.5
OXR - 23
YOX - 1Y40.5

I'm hoping there's a website where I can plug in these values that will
show my existing color and then let me increase the amount of the
BLK/OXR/YOX and see what other colors I might be able to create.

Any suggestions?

Thanks!
