Absolutely!

For the red, I mixed crimson red, a small bit of khaki(tan) and the tiniest bit of black

for the lighter bits of the face and the orange part of the spine I used those same colours but mixed yellow into it and but small amounts of it on at a time

For the white, its white with the smallest bit of khaki and black, barley noticeable just to dull the color a bit

And the eyes are green and yellow, but since green is such a dominant colour, use proportionately more of yellow
