Lack of color in new sourcetree icons makes it harder to find what you need

The new interface buttons don't have any color. Color is important for the interface as it helps the eye find the button you're looking for. If they are all gray I have to focus a lot more to find the button I need instead of subconciously searching for the color, which is faster than recognizing shapes. It's harder even if the button's position didn't change after the update.
