Here, we develop colorschemes for Mathematica:)

How to use

In order to apply a color scheme, you need to import a library file, where the scheme is defined.
On your .nb file, execute

Import["colorschemes.wl"];

and you are ready to go

DensityPlot[Sin[x*y],{x,-2,2},{y,-2,2},ColorFunction->RubySapphire]

The color schemes

RubySapphire

• This is useful, for example, when you visualise temperature.
• The default TemperatureMap contains yellow spoiling the visibility near zero.
• This is my first colorscheme which resolves this problem, clarifying your negative, zero and positive points.
