What does the colorize button actually do?

Discussion in 'Photoshop Tutorials' started by Derek Fountain, Aug 20, 2005.

  1. What does the colorize checkbox in the Hue/Saturation dialog box
    actually do? The documentation says to check it if you want to colorize
    your image, but I can't find a description of what colorization actually is.

    It appears to be similar to the Color blend mode - it keeps the
    lightness of the pixels the same while converting them to a hue of your
    choice. If that's the case, what is the difference between dragging the
    hue slider with colorize checked, and dragging the hue slider with
    colorize unchecked? AFAICS you just seem to get more garish colours when
    the box isn't checked. :eek:)

  2. That is correct.

    If you drag the hue slider without the colorize checkbox checked, the
    hue of all the colors will shift with the same amount, so the colors
    remain different.

    If you check colorize, it has a similar effect to making a duotone image of
    white plus the colour you map to. If you leave it unchecked, it remaps the
    spectrum.

    If you check the Colorize button, Hue and Saturation makes every pixel
    the same hue.

    If you do not, then when you drag the Hue slider, you change the
    EXISTING hue of each pixel--green pixels become blue, for example, or
    purple pixels become yellow--but not all the pixels become the same hue.

    true....but it better with it check so you can see the actual
    color. It just lets you adjust the manually see it....
