If you want decent opening ranges check out upswing poker. They have free opening ranges
Equilab does the work for simple calculation which is more than enough for small stakes poker. Even I personally only use it for now.
Or you can try flopzilla. but it's subscription based
Thanks . I do use all those but I want to make my own custom ones with my own color codes (l want to use a more faded color for lower frequencies etc). So far all ive found in the Jonathan Little range tool but it has a max of 7 colors.
