Question

Colorize images to specific cmyk value

I would like to colorize an entire image to a specific CMYK value (not just manually adjusting the hue to approximate it). I have seen many similar tutorials online, but nothing that does this in a straight-forward way. Any suggestions?

Thanks!

As I understand it, HUE is a conversion of RGB only. So anything that works with hue will be directly converted from RGB, handled as hue, and then turned back to RGB. So, while you can convert that onward to CMYK, you can't specify a CMYK value as a hue.

@Rachel.b.Jackson – Are you referring to the "colorize" checkbox in the Hue & Saturation adjustment?

 

If you are in CMYK mode and wish to specify CMYK values, then a Gradient Map adjustment or a Duotone/Montone mode and back to CMYK again before fine tuning any values.

 

These methods are not exactly the same as hue/saturation colorize.

    @Stephen Marsh Thank you!

    Yeah... I am referring to the "colorize" box. I want to keep the tonality, but change the hue of the entire image to a specific CMYK value. Does that make any sense?

    A "specific CMYK value" is a flat field of monochrome color, period. With tonality it's a range of CMYK values. In other words, your question rests on faulty premises.

     

    You can't use Colorize for this. The closest would be a layer in Color blend mode.

      There is no "straightforward way" because that's just not how it works. It's in fact not even clear what you mean by "colorizing an entire image to a specific value". If you do that, you end up with a monochrome solid. So you really need to clarify what is actually required. From simply using an overly to generate a tint to complicated techniques where everything is separated into custom channels this could be anything.
