if anyone knows how to make a glowing color fade into darkness? its for my new dragon oc for my sylonox account and he has glowing openings on hes neak and face, he is also kinda glossy looking so i need the darkness to blend with him and the light reflect.I have some glow but havent added the dark yet just incase i messed up. If anyone knows could you tell me and explain, still trying to get used to pens. Thanks and have a good day
