I want to get english names of colors from a colormaps object. So far I read that you can get numeric values of colors. For example -
import numpy as np
import matplotlib.pyplot as plt
from matplotlib import cm
from matplotlib.colors import ListedColormap, LinearSegmentedColormap
viridis = cm.get_cmap('viridis', 12)
print(viridis)
print(viridis(0.56))
OUTPUTS
<matplotlib.colors.ListedColormap object at 0x7fb112c73ba8>
(0.119512, 0.607464, 0.540218, 1.0)
It is also clear that LineSegColor is a tuple that matches a string and a dict containing a hash between strings and matrices. Matrices are representing a gradient in some n*m space for the expression of particular color.
cdict1 = {'red': ((0.0, 0.0, 0.0),
(0.5, 0.0, 0.1),
(1.0, 1.0, 1.0)),
'green': ((0.0, 0.0, 0.0),
(1.0, 0.0, 0.0)),
'blue': ((0.0, 0.0, 1.0),
(0.5, 0.1, 0.0),
(1.0, 0.0, 0.0))
}
blue_red1 = LinearSegmentedColormap('BlueRed1', cdict1)
How to reverse engineer the creation of color to Virdis?
