I have some wilton colors (not no-taste red)

I also have these Americolors:
Red Red
Burgundy
Fushia
Super Black
Sky Blue
Copper
Lemon Yellow
Forest Green
Mint Green
Deep Pink
Mauve
Peach

I realize I should have bought a pack that had "super red" now, but...
Is there a way to make a brighter red than what "red red" gives me, which is almost a salmon-ish colored red, with the colors I have?

The forest green didn't turn out very dark either, almost like a medium spruce green. I thought Americolor was suppose to give really bright colors?

Will the Super Black give me a real black that will work for a street?

Thanks in advance!

Put more red red in. Sometimes with red you have to use a lot more than you'd anticipate using.

Super Black will make a real black, as long as you put enough in. It usually darkens a bit overnight (in fondant) so you can stop at dark gray and it will be all the way black the next morning.
