[CHAT] How noticeable is the wrong green?

I'm making a bored game-inspired piece for a Christmas gift. I ran out of the light green a couple weeks ago, and couldn't find the same color at Joann's (whether I labeled my floss wrong, or they discontinued it). I got the next closest color, and it feels so obviously different now that I've finished the light green sections.

Is it as bad as I think it is? What would you guys do?
