Math.random + 1

Why didnt he had the '+1' on the end of the Math.random() function to bring it from 0 to 1 considering the index value?

Hi David,

The Math.random() function used in this video isn't for an index value, it's for a RGB value, which can range from 0-255. If you added 1 to it, the range would be from 1-256, which wouldn't be usable with the rgb function.

Hope that helps!
