Question

Changing color- HSL lightness +/- 100

Hi all!!

I am trying to change the color of a photo in photoshop, to a specific color for my brand. I created a new layer and made a huse/saturation adjustment layer. The HSL of my color is 323, 60%, 70%. However, the lightness scale in photoshop is -100 to +100- the lightness in my color is on the 0 to 100 scale. Is there an easy way to convert the lightness to match photoshop's scale?

thank you!

Melissa

    I suggest that after you have established the HSL you note their Lab Color values and use those numbers for your criteria. There is a vital advantage: Lab is device independent. Your established color will remain constant as you change the Profile from, say,  sRGB to Adobe RGB, etc.  (Note that in the Color Library,  Pantone values are displayed as Lab numbers for this reason.)

    Yes indeed. Lab is the "master reference" for all the other color spaces. With a set of Lab numbers, there is never any doubt which color is requested.

    Open the color picker and punch in your HSL numbers and see how it corresponds to whatever other scale you're trying to match. Of course all these numbers are just relative, so they might appear different depending on the color space you're using.

    So I used the picker but it shows HSB not HSL. It lists H as 323 which is correct, but S as 41% and L as 67%- those are not the correct percentages for the color.

    To define a color you need a color space reference. HSL/HSB is not a color space, it's just an abstract color model without a proper definition. It is relative to just about everything. You really can't use it for anything other than adjusting a color against itself (which is how it's mostly used in Photoshop).

    A defined color would be something like sRGB 125,33,176,  Adobe RGB 32,24,123,  Lab 62,-5,28. These are all specific positions in defined color spaces.
