color_shades: Create custom colormaps using any colors!

color_shades allows you to easily create custom colormaps using different colors from the rgb function (link in the description).

Create your custom colormap using the listed colors within the rgb function (required; download from https://www.mathworks.com/matlabcentral/fileexchange/24497-rgb-triple-of-color-name-version-2).

Example 1: Use a colormap going from green, to yellow, to red, to violet just execute:

my_colormap1 = color_shades({'green','yellow','red','violet'});

Now, let's use it plotting some data:

peaks
colormap(my_colormap1)
colorbar

The result is showed in the image of this function.

Example 2 : Replicate a colormap used in colored infrared satellite images:

my_colormap2 = color_shades({'black','gray','white','steelblue','green','yellow','orange','darkred','pink'});

Using it when plotting satellite or model data you will get something like showed in Example 2 (see figure).

Example 3 : Create a colormap for displaying wind speed from model data:

wind_colors = {'white','azure','turquoise','yellow','orangered','Pink','white'};
my_colormap3 = color_shades(wind_colors);

See figure example 3 to see the result when creating a plot of wind using model data.

Notes:
- You can use whichever number of colors you want. Just be sure of following the syntax of the examples to avoid errors.
- To see the full list of color names, execute rgb chart.
- Function does not support any other input than a cell string.
- Be creative!
