I was wondering how I could find a color "number"
Example: Green = 82 255 7 128
Is there a program or something?

Those are RGBA values (Red, Green, Blue, Alpha). The numbers are ranging from 0-255, and they control the intensity of each channel. For example:
Pure Red = 255 0 0 0
Pure Green = 0 255 0 0
Pure Blue = 0 0 255 0

By changing the values, you change the mix of primary light colors to determine the final color.

The alpha channel is a little harder to understand, as it doesn't control visible light, but a special quality of the texture, sometimes used for bumpmaps or transparency maps. Not all images have an alpha channel.
