thank you for the reply ! yes i later learnt that. so the routine i use itself contain a keyword for color. the routine is:

UMN> my_padplot_both,pd,COLOR=13,UNITS='flux',EBINS=[0L,8L]

Here I need to define colour as an array of long/integers specifying the colors associated with each energy bin value. So I tried :

UMN> my_padplot_both,pd,COLOR=INTGEN(39),UNITS='flux',EBINS=[0L,8 L]

But still I couldnt get the rainbow colours. Is the array of integers I defined wrong ?

By the way UMN is the university of minnesota wind software library i am using it in IDL.
