How do you replace color adjustment layer in Photoshop?

You can replace color adjustments using the Replace Color feature in Photoshop, which does not utilize layers. Here's how:

Using the Replace Color Feature

Photoshop's Replace Color tool offers a way to change colors directly in an image, bypassing the need for adjustment layers in many cases.

Open the dialog: Navigate to Image > Adjustments > Replace Color using the dropdown menus in Photoshop.
Choose a preview option: In the Replace Color dialog box, you can select how you want the preview to be displayed:
- Selection: Shows the mask of the selected color.
- Image: Shows the actual image with the color changes you are making.

Selection: This option will show you a black and white mask, displaying the areas where the color is being targeted for replacement.
Image: Provides a direct view of the changes to color as you make them. This helps in seeing if the replacement is being applied accurately.
Color Picker: Use the color picker to select the initial color you want to change directly from your image. You can adjust the range and selection to dial in on specific colors.
Replacement Colors: You can select which color to use as a replacement.
Fuzziness: This is a slider that controls how much the original color is expanded when making the selection.
Hue, Saturation, Lightness: These adjustments allow you to fine-tune the colors.

Direct Color Changes: Replace Color is best when you want direct, quick color changes to specific areas of an image without the flexibility of adjustment layers.
Targeted Adjustments: It's helpful for adjusting colors in areas where adjustment layers may be more difficult or time-consuming to mask effectively.
Specific Color Replacement: Use this when you wish to change one color for another.

While Replace Color offers a good alternative, adjustment layers are often more flexible for detailed non-destructive workflows.
