How can i put a color to my object?

This is my example, is one text into a loopindex to take 1 to 200 numbers, i can create just i want.

The question is; how can i do one of them are in blue and the others in red ramdonly.

Always i use some code, but when i use it, the item is changing between them, and i want a few in red or a few in blue, odds in red, pairs in blue.... something like this.

Can you help me?

Thanks
