I have an array that is something like this: x = [1000,1200,1300,1250,1340,1020,...]

It goes to about 600 "columns."

Now if I want to take those numbers and turn them into a color spectrum, how do I go about doing that...? I have considered doing it manually and actually write out an if/else statement where it goes through each element and finds out what "bin" that it corresponds to and then assign a color.

Then when putting it together, it will create a "color spectrum". But in my case I just want a visual image of the array which looks like a color spectrum.

I was hoping to avoid that if possible. So is there a shortcut to do what I need without having to brute force it...?

Thanks in advance.
