Using this one as the premise for feedback.
My initial thought on the quarter was, "I hope the inlay color-matched to the orange spots don't make it look like a bowtie against a blue tuxedo." The potential for this to look strange is even greater if using random alignment. I mocked it up, though, and I think there's just enough black/patterning in the inlay to avoid an odd hourglass/bowtie effect.
As currently mocked, the $5 presents you with a tough choice because each of the shades of red base will impact contrast on at least one of the spots. The plain red base makes the pink pop the most but bleaches the blurple a bit, whereas Mandarin Red has the opposite effect on both accounts. Retro is kinda in the middle. All three bases make the lavender spot appear a bit washed out to my eyes, but lavendar also seems to be one of the least bright colors in
CPC's spectrum. If you stick with the spot colors as is, be very careful in choosing your base, and for the love of a straight flush, get color samples if you don't already have them - the more recently produced, the better. I probably lean towards favoring Red or Retro with the spots as is, personally, but your eyes may well see the colors differently.
For the $25, stick with the 3TA316 pattern. The other one makes for an odd progression between the $5 and the hundo. I agree, having the 3T14 would be a nice option, but alas...I think the mock you had with the 3TA316 looked pretty good, and the DG Green should contrast plenty with the Green base. The Dark Green spot will actually have the least contrast against the base. Have you considered dropping the dark green spot in the middle of the other two in order to accentuate it a little bit more?
Your hundo is legit. I'm not typically fond of using the 14 or 12 inserts in the pies, but you've done a nice job with it here.
But dude...that $1...it needs help. The 8A14 is fine, but it needs something, and that something is color. Not a lot, though. I think this is one instance where Dark Blue can actually be your friend. It still conveys the same effect, but gives it *just* a little something so that your brain doesn't scream "What's with the black & white photo?" I'd also be curious to see what it would look like with the lines in the inlay altered to the dark blue instead of grey.
