Well there's various ways of achieving a simple spot colour.
I'll assume you have photoshop or photoshop elements, but it can be achieved in paint shop pro & others.
open your photo. in PS, you should now go to the 'Layer' menu on the top bar. Click 'New Adjustment Layer', select 'Hue/Saturation'. In the dialog that comes up, slide the Saturation slider (middle one) all the way to the left.
now, whenever an adjustment layer is created there is always a 'Mask' created. If you look at the Layers Palette (if it's not visible press F7 on the keyboard (if you're windows based, don't know if it's the same on Mac), you'll see that the uppermost layer (which should be the 'hue/saturation' layer) has two little thumbnails. The right hand one, a white rectangle, is the mask. Click it to make sure it's selected.
Select the Eraser tool, and erase where you wish the colour to come back thru.
Using this method, you will not harm the actual image.
Experiment with other adjustment layers too.. Curves is useful for exposure control of a sort, brightness/contrast, channel mixer (neat trick on landscapes with lots of dramatic cloud, select the following settings in this order +112,+100,-122 & click monochrome). You can also adjust the layer 'style' for each adjustment layer, see where it says 'Normal'? Scroll thru the list and see what happens.
Also if you had a curves layer to darken the sky, but wanted the foreground to be normal, create the layer, select the Gradient Tool, making sure it's black to white. On the curves layer mask, go to the image, drag the tool across the page, top to bottom or bottom to top.
Hope that helps
