Methods

`Static`correct

correct(color: LinearRgb, type: CvdType, severity?: number): LinearRgb
Corrects a color to make it distinguishable for color-blind users. Uses the "Error Diffusion" method: calculates the information lost during simulation and shifts it into a visible spectrum (e.g., shifting lost Red/Green info into Blue/Lightness).
Parameters
- color: LinearRgb
  The original color.
- type: CvdType
  The type of color blindness to simulate.
- severity: number = 1.0
  The severity to correct.
Returns LinearRgb
The corrected color.
- Defined in functions/Cvd.ts:53

`Static`simulate

simulate(color: LinearRgb, type: CvdType, severity?: number): LinearRgb
Simulates how a color appears to a person with CVD. Based on Brettel/Viénot/Mollon algorithm via Linear RGB projection.
Parameters
- color: LinearRgb
  The original color.
- type: CvdType
  The type of color blindness to simulate.
- severity: number = 1.0
  The severity to correct.
Returns LinearRgb
The deteriorated color.
- Defined in functions/Cvd.ts:145

`Static`simulateFrom

simulateFrom<C extends Color>(
    color: C,
    type: CvdType,
    severity?: number,
): LinearRgb | C
Simulates how a color appears to a person with CVD. This is just a wrapper of simulate().
Type Parameters
- C extends Color
Parameters
- color: C
  The original color.
- type: CvdType
  The type of color blindness to simulate.
- severity: number = 1.0
  The severity to correct.
Returns LinearRgb | C
The deteriorated color.
