contour graph plotting and editting

Hello everyone,

I have this contour graph. I require the white part of the graph to be same colour as the relative humidity at 0%. How do I do this?

I have attached my graph and code to this question.

Thanks in advance

Thanks a lot :)

Be kind to yourself and use arrays next time, instead of manually writing every combination. You can use ndgrid, bsxfun, or .* to achieve that same result. repmat might also be useful.
