DAWG Tools - OKlab Color Inspector PRO

DAWG Tools - OKLab Color Inspector PRO - Perceptual Color Tools for Unity

Unity’s default Color.Lerp interpolates colors in RGB component space.

https://dawgtools.org/unity/

For UI and theme transitions, this often results in:

• Desaturated or “dirty” midpoints
• Perceived brightness dips
• Unintended hue shifts
• Inconsistent animation quality

The OKLab color space is designed so that distance and interpolation better match human perception.

This tool makes the difference visible, measurable, and actionable inside the Unity Editor.

OKLab interpolation produces smoother, visually consistent gradients and transitions because it operates in a perceptual color space rather than raw RGB component space.

Instead of guessing how a transition will look, you can:

• Compare Gamma RGB vs Linear RGB vs OKLab interpolation
• Inspect perceptual midpoints
• Measure ΔE distance between colors
• Validate contrast compliance before shipping

1. Typical Workflow

1. Select two UI colors (e.g., Normal → Hover).
2. Compare Unity RGB interpolation against OKLab interpolation.
3. Inspect midpoint, hue drift, chroma, and contrast.
4. Replace Color.Lerp with OKLabColor.Lerp in runtime code.

2. Who It’s For:

• UI / UX engineers
• Technical artists
• Tools programmers
• Teams implementing dynamic themes
• Developers who care about visual polish and accessibility
