I think I am also leaning towards the no bonus territory idea.
OK here is an idea for the naming. If we use a grid system then the names do not need to be in the way and there is no need to use colors to shorten the name.
1) One color - Grid naming: A1, A2, ..... Q14, Q15
2) Color Naming (See last image) Red A, Red B ..... Blue Q, Blue R
This is confusing because I think people will think the different colors mean something. There will be tons of posts "Why don't i get a bonus for holding all of RED?
3) One color - pellet naming: A, B, C, D.....AA, AB, AC, AD,......EA, EB, EC, ED
I like #1.
But we still need to decide if we want to lower the bonus as the numbers get higher (read lower right of legend)
