Thanks, courage. A few thoughts in response.
As to the colors, I tried as much as possible to use colors not found elsewhere in this draft of the set. This is what directed me toward blue (rather than retro or light as in the frac), green (rather than retro or light as in the quarter), and light choc (rather than choc as in the $5). I couldn't avoid the red, pink, and black from the hundo (mandarin looks close enough to retro imo that changing it out would be pointless and regular pink is too close to lavender imo), but I'm not that worried as the hundos wouldn't be on the table very often at all with all the racks of $1s.
As to the 214 pattern, it seems the best option when accounting for price, but if I were a billionaire I'd probably go 418. That represents a .75/chip difference in price. I think the 214 and 418 patterns are close enough in effect for this purpose to make me not want to spend the extra $750.
The only thing that makes me a little reluctant is I'm not really sure how I'll feel using mixed colors during big bet games and big bet games will be far more commonly spread than limit. I have considered doing 300 with red spots and 100 of each other color and only using the reds during big bet games. Not sure I like that idea much either, though. Still noodling...
