You already have color on the mind because you know the meaning of this kanji, so think of something colorful about yourself. Imagine your ear (いろ) being a weird color... green, purple, red, whatever. Just make it really bright and standing out.
You can even have someone ask you about your ear... "Is your ear okay? I think it's the color blue..."
