Set specific colors in colormap

Hi Everyone,

I want to set my desired colors in colormap such that all negative values of a trend are different shades of red, all positive values are different shades of blue, and the value zero is either white or gray. How do I go about that please?

Thanks

you should look in the File Exchange section, there are plenty of code available for custom colormap
