Typically that color is fine but you know that umpires/leagues can interpret the rules in different ways.
Here is the rule from the MLB rule book:
(a) The pitcher’s glove may not, exclusive of piping, be white, gray, nor, in the judgment of an umpire, distracting in any manner.
(b) No pitcher shall attach to his glove any foreign material of a color different from the glove.
© The umpire-in-chief shall cause a glove that violates Rules 1.15(a) or 1.15(b) to be removed from the game, either on his own initiative, at the recommendation of another umpire or upon complaint of the opposing manager that the umpire-in-chief agrees has merit.
So if the umpire deams the glove color to be distracting he could remove the glove from the game.
I think the glove color is fine but do you want to temt or challange the ump that wants to take control of his field, or an opposing manager being a total a hole.
