Hey Kaede,
Don't be scared to use your blush, play with it one day to see what you feel comfortable doing with it.
In the meantime, get a little bit of the blush, and rub it on the back of your hand, then apply it to the apple of your cheeks and blend it back towards your hairline. If the color is too bright, put your blush on BEFORE you put on your foundation, then when you apply your foundation, it will mute it down.
Another options?....apply your blush with the same makeup sponge (and I hope you are using disposable sponges) that you put your foundation on with. It will mix with the remaining amount of foundation and come out softer on your cheek then it would if you applied it directly.
