High Contrast Parula-like Colormap Generator
Author: Yong Hoon Lee (http://yonghoonlee.com, ylee196@illinois.edu)
This is a monotonic and linear grayscale intensity colormap with an increased contrast for grayscale printout readability. The colormap looks similar to Parula, but this code does not contain any formula, code, colormap scheme, or specific knowledge that MathWorks, Inc. generated or developed. Note that the original Parula colormap was created by MathWorks, Inc. and a default colormap in MATLAB.
RGB = MODIFIED_PARULA() generates a N=64 level colormap in RGB format.
RGB = MODIFIED_PARULA(N) generates a given N-level colormap in RGB format.
