I'm making a bobcat cake, so I need a really bright orange.
How do I mix a bright orange?

red & yellow makes orange right?
i have golden yellow, lemon yellow, Dora teh Explorer red (roughe) and no taste red. any suggestions?

i would try to combine red and yellow. different ratios will give you different shades but you should be able to get a bright orange. Maybe go for the lemon yellow and one of the reds.

I think golden yellow with a touch of no taste red. The golden yellow is a yellowish-orange color so you wouldn't need too much red.

I would use Americolor's Electric Orange. Americolor gels mix really well and you only need a little bit. Best part is the colors are really a "true" color. Once I used Americolor brand I never went back to Wilton.
