Mathematica colours
Mathematica has a rather extensive support for colors, but more often than not, it needs tinkering with.
Colors can be retrieved from hexadecimal codes with a # in a string:
RGBColor["#0e64fc"]
We like to use the SunsetColors color scheme:
ColorData["SunsetColors"]
A more serious and clear scheme is to blend between red and blue with white as an intermediate. We use this for convention for bunching/antibunching (white is uncorrelated):
ColorFunction -> (Blend[{White, Blue, Red}, #] &)
This module exports a list of n colors distributed along the gradient:
lcol[n_] :=
Module[{}, Table[ColorData["SunsetColors"][i], {i, 0, 1, 1/(n - 1)}]]
A blending of colors can be done with blend, e.g., that generates a smooth transition from red to blue in n steps:
Table[{Blend[{Red, Blue}, x]}, {x, 0, 1, 1/(n+1)}]
In ListPlot, to have points (markers) have the same color as the lines (which should be the default), add:
PlotMarkers -> Graphics@{Point[{0, 0}]
The default colors in modern versions of Mathematica is taken from: [1]
ColorData[97, "ColorList"]
One can find the other useful themes [2]
"Color"/. Charting`$PlotThemes
(* BackgroundColor, BlackBackground, BoldColor, ClassicColor, CoolColor,
DarkColor,GrayColor, NeonColor,PastelColor, RoyalColor, VibrantColor, WarmColor,
DefaultColor, EarthColor, GarnetColor, OpalColor, SapphireColor, SteelColor,
SunriseColor, TextbookColor, WaterColor} *)
Grid[{#,Row@(("DefaultPlotStyle"/.(Method/.
Charting`ResolvePlotTheme[#, ListPlot]))/.
Directive[x_,__]:>x)}&/@("Color"/. Charting`$PlotThemes),Dividers->All]
