How to replace color in Photoshop to specific Lab color?


Question

I know how to replace a color in Photoshop (by going to image -> adjustments -> replace color and selecting the color etc.) however I need to match specific Lab colors provided by my client in order to show the same product photo in a variety of different colors. Even though I put the specific Lab numbers after clicking the replacement swatch, it doesn't even come close to matching on my actual photo. The original base color of the photo makes a big difference in the end result.

Any suggestions or alternative methods on how to approach this would be much appreciated.

Thanks!

You'll get better results if you start by:

  • Going to Edit > Convert to Profile

  • Choosing Lab Color:

Convert to Profile dialog

Without doing this the colors will change slightly.

You're still not going to get 100% accurate results from the 'Replace Color' adjustment in my experience...

Better off to just do a straight color overlay if possible.

  • New layer

  • Fill selection with desired Lab color (after converting the document to Lab Color of course)

But I'm not sure what this person specifically was selecting so this may or may not have been feasible in that case.

Replace color can get you pretty darned close. Most people would not be able to tell anyhow (my opinion)... Might need minor adjustments.

The hard part is getting a good selection
