from_wavelength(wavelength)

Generate a colormap with a minimum of black and maximum color approximately corresponding to a wavelength in nanometers.

RGB value approximating the given wavelength is calculated using Eq. 4 from [1].

Parameters:

wavelength (int) – wavelength to approximate maximum color from

Examples

# plot the blue image from a kymograph with cyan colormap
kymo.plot(channel="blue", cmap=lk.colormaps.cyan)

# plot the blue image with the emission maximum of the fluorophore excited at 488 nm
kymo.plot(channel="blue", cmap=lk.colormaps.from_wavelength(521))
