Hi BrowserUK,thanks allot,that really helped,I was able to get some quick results.
However,I will be concerned about the granularity of this,and also,because my values have a peak of 485 now, it's all shown in a blue nuances.
But soon I will probably have higher values , maybe 1000,maybe 10000 ...
it's not as easy as I thought(looking on your code) to deal with those high numbers as well.
I will look more into your code and the color ramping link http://local.wasp.uwa.edu.au/~pbourke/texture_colour/colourramp/
was excellent, thank you :)

P.S. : perlmonks seems to always be full of knowledgeble people , of all the places I'd ask,I didn't expect
the answer would come from here
