depvisionquest  wrote I'm sorry, but I've totally forgotten how to do this.     What do I do pr where do I go in Elements to make a blue sky bluer?   Or darken any other specific color in a photo? Thanks...................

1. Make a selection of the sky or the object using one of the selection tools, e.g. lasso, selection brush
2. Place the selection on its own layer (CTRL+J)
3. Open a Hue/saturation adjustment layer above this, and link these 2 layers (CTRL+G)
4. Work the 3 sliders to best advantage
