If you're going to brighten your darkness with a bold dash of color, go all the way with an aggressively electric lime green! It's bright and cheerful without being eye-searing, or crossing the line into ambiguously yellow tennis ball territory. It looks like candy, or slime, or fresh spring grass, or all those things. You probably shouldn't lick it.
In order to maintain the vibrancy of the color, this sock was sewn with a white elastic base. This may show through the stripes when the socks are stretched, but should not noticeably affect the design.
