Quick Photoshop question

Im struggling with this a tad, still learning and playing about just now.

What ive done is chosen a brush and drawn a few wee shapes in black, how can i go about changing the colour of these shapes without having to draw them again?

Thanks

Select them, change the color in the palette, then use the fill tool.

Sorted now, thank you.

Also, if they're on their own later, you can always do Layer->Layer Style and set a fill color. Lots of ways to skin that cat, actually.
