I want to resemble how objects look in the far distance, so I need to shift the colors in the objects to some bluish tone where the farther the object the closer the color is to the one in the sky. At the moment I just copy the objects in the foreground, change the scale, remove a bit of saturation in HSB color space, and then change some values in RGB or CMYK color space moving the values closer to blue in the sky. This procedure is error prone and require multiple interactions, so I was wondering whether there is a plugin or a third party tool or something I can use to speed up the process.
For instance, in this case I change the blue component in RGB color space to the bluish side.
Some times it's no clear what direction to move the handles in RGB color space so I need to change to CMYK color space.
