Platinum and Diamond icons are lack luster

Hey I have gotten feedback from many people agreeing with me that the Diamond and Platinum season 5 ranked icons are just lacking some color.The designs are perfect but the platinum one looks just like the silver one with a very slight, barely noticeable tint, and a green gem rather than a blue one. The diamond one is not bright at all, especially in comparison to the gold one which is even lower tier. I think if you guys increased the brightness on both of them, or maybe the tint of the teal platinum color on the platinum icon, they will be perfect.
