How to recolor a photo using specific RBG values?

I have ten specific RBG values that I want to recolor a full image with, but I don't want to convert the image into a 10-color image and lose the range of colors between the main ten colors. I want there to be hundreds of colors, but within the range I'm looking for. Kind of like a custom photo filter.

I'm used to Illustrator and Photoshop is pretty new to me. Your help is greatly appreciated!

RGB, right? RGB values alone do not define colour.

For example, a particular RGB triplet may produce a colour which appears quite different if assigned Adobe RGB to when the same image is assigned sRGB. SO your colour numbers have to come with a workig space (then, in the background, that document ICC profile defines them relative to human vision using XTZ or Lab colour)

I hope this helps

Hi @Raina22179513vu8t - I’m Caroline, a Product Marketing Manager at Adobe.

I'm conducting some research on recoloring assets and think you'd provide some super valuable insights - would you be interested in a brief interview? We'd also offer a gift card for your time!

Reoder RGB values, can you be more specific with a numeric example?

You have an RGB value (in some color space) of say R20/G89/B123 and you want the new value to be another specific triplet?

I'm probably not wording myself in a way that makes sense to people with an understanding of Photoshop's features. Like I said, I only understand a few of the basic tools in Photoshop, practically a complete beginner. I'm hoping you can help me get from Point A (literally just opening a JPEG in Photoshop) to Point B (having the image colored the way I need it).

The 8 (its actually not ten I just checked) RGB values I'm need the image to follow are:

R B G

131

128

120

207

187

167

69

53

56

213

175

151

48

22

23

92

141

81

176

94

82

The unmodified image has infinite colors currently, but I'm looking to create some kind of guide for the colors to follow that way there are still infinite colors, not hues that fall outside my ideal color palette. I hope that makes sense.

I'll look forward to someone telling you how to crack this nut, as I am not sure its possible

Where do those RGB values come from? My 10c says that it's not going to be possible to define image gamut with just a few RGB numbers, I'm afraid.

I hope this helps
