mycolorpy 1.5.3

A scientific visualization toolkit for generating dynamic color arrays from any colormap

mycolorpy

A scientific visualization toolkit for generating dynamic color arrays from any colormap. Contains functions to create an array of colors based on a colormap.

Installation Instructions:

You can pip install it using:

pip install mycolorpy

You can then do:

from mycolorpy import colorlist as mcp

Example: To create a list of 5 hex strings from cmap "winter"

color1=mcp.gen_color(cmap="winter",n=5)
print(color1)

Output:

['#0000ff', '#0040df', '#0080bf', '#00c09f', '#00ff80']

Another example to generate 16 list of colors from cmap bwr:

color2=mcp.gen_color(cmap="bwr",n=16)
print(color2)

Output:

['#0000ff', '#2222ff', '#4444ff', '#6666ff', '#8888ff', '#aaaaff', '#ccccff', '#eeeeff', '#ffeeee', '#ffcccc', '#ffaaaa', '#ff8888', '#ff6666', '#ff4444', '#ff2222', '#ff0000']

There is a python notebook with usage examples to better visualize this.

Say you want to generate a list of colors from a cmap that is normalized to a given data. You can do that using:

a=random.randint(1000, size=(200))
a=np.array(a)
color1=mcp.gen_color_normalized(cmap="seismic",data_arr=a)
plt.scatter(a,a,c=color1)

Output:

You can also reverse the color using:

color1=mcp.gen_color_normalized(cmap="seismic",data_arr=a,reverse=True)
plt.scatter(a,a,c=color1)

Output:
