Alter hair/dress colors-Hulp!

I have a friend who wants me to do "Two little things" to an otherwise cool picture of two models.

I. First, he wants that I should make the honey/ash blonde model's hair, brownette. And the Brownette model's hair, honey/ash blonde (no, he does not want me to just exchange their hair, or move their heads - "simply" exchange the colors!!).
2. Secondly, the blonde is wearing a white dress, the brownette a vivid red dress. Yep, you guessed it, he wants me to reverse the colors. How to make the white take a red color? How to make a dark color except white (or any other color for that matter)?

These challenges are probably related, right? I need to preserve the textures of hair and fabric while changing the hue to a predetermined level. Can it be done? How?:

:confused:

could you pls sent me a 100-200 kb jpg to see the picture?
hair color change to honey ash is very, ver difficult.

To darken the hair is easy, but the opposite... Perhaps cutting and pasting the hair is more suitable . For the dresses, use hue/saturation/lightness.

Take a look:

Cutting and pasting hair? That's completely absurd.

If you just want to change the color of hair (applies to anything else as well), select the area in the image where the hair is (either with Pen, Quick Mask, Lasso, or Magic Wand, whichever you prefer), and adjust Hue and Saturation (CTRL+U). Play around with the sliders until you get it just right.

If the Hue/Saturation method doesn't go too well, grab the color of either the blonde or the brunette, fill the selection you made over their hair and change the blending mode to something like Color. If the color initially is a bit off, try desaturating the hair in the source layer.

Channel mixer works better when changing from Dark---»Light color.

Accurate selections—however you create them—are the most important thing. Create Layer MAsks and use Adjustment Layers to experiment, so you're not permanently altering the original image data.

Yes, darkening the hair is quite easy. For a quick tutorial about lightening the hair, check out the link below. I have used this technique many times and it works better than anything else I have found.
