Both of those are really good rainbows, except the 1 is a bit of a weak yellow when placed right next to all of those other numbers.

funny, there's the color "blue" (it's "BLEU" in french) in your letter-rainbow!! ^^

mines are 251439 (red-orange-yellow-green-blue-purple)
it's harder with the letter, something like
M -(c/j) - i a u e w : I don't have any orange letter, but it could be a mix between a c and a j

7 9 8 3 l 4 f

That's the best I can do; I don't really have a good violet, and some of these have more than one color (8 and 9 especially).

7 9 a 8 5 3 u l 4 f
