Hi! Thank you for making this icon, and I apologize for not giving feedback any sooner. The change I did was minute, making it a bit brighter but keeping the contrast intact because, simply brightening the image would make it closer to whitening including the supposed dark aspects of the icon, like the wood of the axe, or the color of the axe itself.
If this change is considerable to you, I can send them to you in the DMs. I also redid the disabled version for the command button and passive button icons.
