Color Compensator

About this plugin

Stop guessing transparency values.

Compensator helps you find the exact semi-transparent (Alpha) color that looks visually identical to a solid color when placed on a specific background. Perfect for creating adaptive design systems, hover states, and overlays that match your brand guidelines.

🔥 Key Features:

Smart Calculation: Input your Target Solid color and Base Background — get the mathematically perfect Alpha color instantly.

↓ Smart Pick from Selection:

Pick a Solid color to copy it.

Pick a Semi-transparent layer, and the plugin will automatically “flatten” it against your Base Background to find the visual Solid value.

Presets System: Save your favorite background sets (Light Mode, Dark Mode, Paper, etc.) and preview how your calculated color looks on all of them simultaneously.

Multi-Format Support: Works with HEX, RGB, HSL, and HSB models.

One-Click Actions: Apply the calculated color to selected layers or generate a sample frame with one click.

👇 How to use:

Select your Target Solid (the color you want to achieve visually).

Select your Base BG (the background color underneath).

Get the result! Adjust opacity manually if needed.

Check the “Preview on backgrounds” list to see how this alpha color behaves on other surfaces.

Why do you need this?

If you simply reduce opacity, colors often look washed out. This plugin calculates the compensated color values so that Color A at X% Opacity on Background B looks exactly like your original Target Color.
