This might be a good idea or maybe not. But it will be nice to have more then one markings. People can make their char match their presets or close to it. Also, you can change the other markings to a different color like if you have a brown marking, you can change the secondary markings to a different color to pink or red if your using scars markings on your chars.
but this will be a slightly bad idea due the fact people love to make neon chars. so, it's a good idea and a bad idea at the same time
