heatmap color scales

guslI'm programming something that makes color plots.
If I interpolate linearly between blue and red, I end up with different shades of blue, red and purple.
But most heatmaps also have greens, yellows and oranges, which I think do more good than harm.
Is there a standard path through the RGB color cube?
