Dear all,

I need some help with regards to colormaps, I am new to python and unsure

how to go about it.

I have three spatial correlation maps, lets call the A(72x144), B(72X144)

and C(72x144) and each one of these are made of of values from -1 to 1.

Now I want to generate one single colomap form these based on the following

conditions,

For regions where A > 0.5, B > 0.5 and C > 0.5, make those regions red on

the new color map, for regions where A>0.5, B = 0 and C = 0 also make those

regions Blue.

In a coding format I want something like this

For in range(x):

for J in range(y):

if A(i,j) >0 & if B(i,J) > 0.5 & if C>0.5:

then colormap = Reds.

This is the general idea I have but dont know how to write this and make it

actually work with my code.

I am open to anwer further questions and I would be most grateful for your

help.

Thanks

Adam.
