Color enhancer brings back the full color control to the user. In the past the only possible adjustment was the modification of red, green and blue gain. Color enhancer is much more powerful here. You can select any color from RGB or CMYK color model and change saturation, hue and lightness. For each channel you can also adjust the tolerance for this applied change.
As you can see this change applies to the sky and not to the remaining picture. Also the white balance is not affected which is a big issue using the conventional way. This enables a much more advanced adjustment compared to the past.
