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:
