Red color palette for gnuplot

I am looking for a palette in gnuplot for red color from very-light-red to deep-red. I found a script for black here http://gnuplot.sourceforge.net/demo_5.3/pm3dcolors.16.gnu

I tried by changing set palette functions red, red, red in the above script, but it is not working.

By "legend" do you really mean "palette"? The legend is the list of plot titles and samples; entries there will normally appear in whatever color the corresponding plot used. The palette is the color gradient used for pm3d plots. To define a gradient from white to deep red:

set palette defined (0 "white", 1 "dark-red")
test palette

If you want more precise control over how light/dark the two extremes are you can provide instead hexadecimal descriptions of the RGB components. E.g. the above command is equivalent to

set palette defined (0 "0xffffff", 1 "0x8b0000")
