sciris.sc_colors

Handle colors and colormaps.

Highlights:

• Adds colormaps including 'turbo', 'parula', and 'orangeblue'

• hex2rgb()/rgb2hex(): convert between different color conventions

• vectocolor(): map a list of sequential values onto a list of colors

• gridcolors(): map a list of qualitative categories onto a list of colors

Functions

alpinecolormap	This function generates a map based on ascending height.
arraycolors	Map an N-dimensional array of values onto the current colormap.
bandedcolormap	Map colors onto bands of hue and saturation, with lightness mapped linearly.
bicolormap	This function generators a two-color map, blue for negative, red for positive changes, with grey in the middle.
colormapdemo	Demonstrate a color map using simulated elevation data, shown in both 2D and 3D.
gridcolors	Create a qualitative "color map" by assigning points according to the maximum pairwise distance in the color cube.
hex2rgb	A little helper function to convert e.g.
hsv2rgb	Shortcut to Matplotlib's hsv_to_rgb method, accepts a color triplet or a list/array of color triplets.
midpointnorm	Alias to Matplotlib's TwoSlopeNorm.
orangebluecolormap	Create an orange-blue colormap; most like RdYlBu but more pleasing.
parulacolormap	Create a map similar to Viridis, but brighter.
rgb2hex	A little helper function to convert e.g.
rgb2hsv	Shortcut to Matplotlib's rgb_to_hsv method, accepts a color triplet or a list/array of color triplets.
sanitizecolor	Alias to matplotlib.colors.to_rgb, but also handles numeric inputs.
shifthue	Shift the hue of the colors being fed in.
turbocolormap	NOTE: as of Matplotlib 3.4.0, this colormap is included by default, and will soon be removed from Sciris.
vectocolor	This function converts a vector (i.e., 1D array) of N values into an Nx3 matrix of color values according to the current colormap.
