MatLab has eight short names for colors, which are: r, g, b, c, m, y, k, w. I want to add new short names for my own colors. Does anyone know how to do it?
I suppose that it is not possible by standart matlab functionality, but I am aware about "Undocumented Secrets of Matlab-Java Programming" book by Yair Altman, and maybe there is someone who is enough proffesional in it?
I know about workarounds, but I need only exactly what I want :)

You can ask Yair Altman (link) yourself!
He was here on MATLAB Answers a few hours ago.
Be sure to post back here with his reply to your inquiry.

No. They are hardcoded into function colstyle for validation purposes. On OS-X that is part of libmwhgbuiltins.dylib

It's trivial.
You can add the code to your startup.m file or your specific m-file. For example to create dark versions of 'r', 'g', and 'b', you can do
darkRed = [0.5, 0, 0];
darkGreen = [0, 0.5, 0];
darkBlue = [0, 0, 0.5];
% Plot something in dark green
plot(1:10, '-*', 'Color', darkGreen);
Note that you have to use the 'Color' option rather than just using it in the linestyle specification. You can define any color with any name you like by specifying any 3 number vector with values between 0 and 1.
