I'm trying to figure out which electronics I need to buy for my first saber, and it has come down to a decision of colors. I want a bright yellow blade more than anything, but if they're not bright (they seem to be lower on the lists), I'll do a green. I've read over posts and looked over pictures, but I think my dilemma needs the advice of personal experience or opinion. If some of you enlightened veterans could throw your two cents at me, I would very much appreciate it.

My questions;
What is the best way (budget/beginner minded) to get yellow? I've heard a white p4 with a filter, but is that really bright enough to make a convincing light saber?

Is a yellow blade of any kind close in brightness to a pure green led?

If a white w/ yellow filter is okay, are there any other fun filter colors that would be worthwhile as far as brightness goes?

I plan on using a cheap hasbro board of some sort. Does that limit me with these color options?

...again, I'm rooting for yellow...
