Open Creative Settings › Aberration to control how colors separate as light passes through the glass.

Mode

Choose Off, Continuous, or RGB Split.

Off

Disables color separation. Defocus is controlled separately by F-Stop and Focus Shift.

Continuous

Spreads colors across the spectrum. Use Hue Rotation to change the colors in that spread.

RGB Split

Separates the red, green, and blue channels. Use it for faster but lower fidelity aberration.

Strength

Increase Strength for more color separation. Reduce it for a more subtle result.

Hue Rotation

Changes the colors in Continuous mode.
