changing a color completely

I have a picture with a burned out sky which is not recoverable. In LR, I can mask the sky and select a blue color from a color pop-up and adjust the color hue and saturation until I get a reasonable fascimile of a blue sky.

I also have a picture that has an overexposed sky which -is- recoverable in C1 but it has some brown tones to some of the clouds. LR portrays these clouds as a neutral gray. I would like to remove the brown from the clouds and make them a neutral gray. I have tried adjusting saturation, kelvin, and tint but that doesn't do the trick. From my experiments with the color tools so far, it looks like they can be used to change the tint and saturation of a color and push it towards neighboring colors on the color wheel a little, but I don't know if/how I could go about actually changing one color to another color in C1.

How would I do this in C1 (can I)?

  You can up to a point but if there is no data (or almost no data) in the burned out areas in the firstplace you won't achieve much by trying to change the colour. You might try cloning in a layer but if you are a talking about a large area it may not be worth the effort. That sort of work is not really what C1 is about.
  
  That's the point where software that originated in companies working in the area of graphics before digital cameras conquered the market can borrow techology from other family members and why C1 supports the option of using external editors.

  Thanks for your reply, Grant.
  
  In the second scenario in my original post, the highlights are not totally blown. The sky is overexposed but I can pull the exposure back to a normal level. I do see some brown in the clouds that I do not want. I would like to understand how to "paint over" the sky with an adjustment layer (I guess that's what I would do) with the adjustment layer a different color. Maybe a layer with whatever color would be opposite brown on a color wheel? I don't know hardly anything about color theory so I'm in the dark about what the image would need. My question is, in general, how would I change the color of a specific part of my image? Does my question make sense? I'm coming from LR where I can create a mask and click on a color chip to change the color of the image area being masked.

  You don't mention which version of Capture One you have, CO10 is a bit different from CO11. Either way you will need to find the Layers tool (in CO10 it is called Local Adjustments, CO11 it is called Layers) and press the + icon to create a new layer, name it if you want. Press the B key to activate the brush (draw mask) tool, or click on the brush icon in the layers tool. Where ever you paint with the brush on the image this will be your new layer mask, right click to adjust your brush settings. Press the M key to view the mask. All of the tools that have the little brush icon next to them will effect the layer mask only. The tools that do not have the brush icon are global adjustments and can not be used solely on the layer mask.
  
  Additionally you can click and hold the brush icon if you want to switch to the erase mask tool or gradient mask tool. Click and hold the + icon to make clone & heal layers and use the brush to clone or heal, alt selects the source.
  
  
  So for your burnt out sky click the + icon to make a new layer, then the B key for brush (or G key for gradient tool) and mask your sky, M key if you want to see the mask while your working, then go to the Exposure tab with the brush icon next to it to reduce the exposure, and use any of the color editing tools to remove the brown color cast. In CO11 Once you are done making adjustments to your layer go back to the Layer tool tab and click on the Background layer and the tools will return to global adjustment tools.

  Thanks for the suggestion! I tried that, though, and it didn't work for me. I was able to fix it in LR by masking that part of the sky and then adding a blue tint. I don't want to just remove the color cast; I would like to totally replace the brown color or kind of "paint over it" with a different color. Can I do this with C1 v11?

  To get rid of the brown patches in the clouds, use the advanced color editor: click on its eyedropper and then click the brown patch. Then either reduce the saturation, or shift the hue a bit. You probably have to click the same patch multiple times and then shift each sample to build up the shift to a blueish hue. (the max range in shift is rather small, that's why you need to do it repeatedly. Luckily the shift accumulates over multiple samples.)
  
  If the brown is in other parts of the image, do the above in a layer with a mask on the sky.
  
  HTH,
  Peter.
