How do you get the animation to come out faded like that, that it can be seen but not so much as others are. If anyone knows what I mean, please comment. Help is most appreciated and if you can point me to a tutorial on how to do it (I know how to do animated icons already, but I want to know how to make faded ones like above and such), that'd be really helpful.
