Question: How to give a specific color in my plot 3d (MAPLE 8)

I want to run a specific color red outside and yellow inside on my equation here using MAPLE 8.00:

plot3d([(0.5+cos(5*u))*sin(2*v),(0.5+cos(5*u))*cos(2*v),0.5*(cos(5*u)-0.3*cos(15*u)+0.02*cos(25*v))],u=0..2*Pi,v=0..2*Pi,axes=FRAMED);

is there some one here can help me? thanks...here is the example of color I want Eg:
