rgb_and_colorbar

colorsynth.rgb_and_colorbar(spd, wavelength, axis=-1, spd_min=None, spd_max=None, spd_norm=None, wavelength_min=None, wavelength_max=None, wavelength_norm=None, **kwargs_colorbar)

Convenience function that calls rgb() and colorbar() and returns the results as a tuple.

Parameters:

• spd (ndarray) – a spectral power distribution to be converted into a RGB array

• wavelength (Quantity) – the wavelength array corresponding to the spectral power distribution

• axis (int) – the logical axis corresponding to changing wavelength, or the axis along which to integrate the spectral power distribution

• spd_min (None | ndarray) – the value of the spectral power distribution representing minimum intensity.

• spd_max (None | ndarray) – the value of the spectral power distribution representing minimum intensity.

• spd_norm (None | Callable[[ndarray], ndarray]) – an optional function to transform the spectral power distribution values before mapping to RGB

• wavelength_min (None | Quantity) – the wavelength value that is mapped to the minimum wavelength of the human visible color range, 380 nm.

• wavelength_max (None | Quantity) – the wavelength value that is mapped to the maximum wavelength of the human visible color range, 700 nm

• wavelength_norm (None | Callable[[Quantity], Quantity]) – an optional function to transform the wavelength values before they are mapped into the human visible color range.

• kwargs_colorbar – Any additional keyword arguments needed by colorbar().

Return type:

tuple[ndarray, tuple[ndarray, ndarray, ndarray]]
