I've just started to learn pygame, and it pretty much needs some coordinates and points in the code in order to position the object. Do you know of any tool or application that I could use as a reference so that I could see a visual representation of the points. 
Maybe a grid with numbers. 
And pygame also includes declaring the color by using numbers. 
Do you know of any site or application that I can use as reference to those numbers and corresponding color. Like this one: 230, 170, 0 And what do these numbers mean.
I'm using windows operating system.
You don't need a grid to help you, you just need to know the origin point (easy - it is one of the corners). Since it is all interpreted, I say you just hack around displaying stuff on the screen till it clicks in your head.
The other part is easy. It is Red, Blue, Green (each one goes from 0-255, 0 is no-color, 255 is full-color).
