Interpolate colortable

Hi all,
I would be very interested in having the EOSSpectral11 colortable with more colours (i.e. with more rows in the triplet wave). So I tried to interpolate the M_colour triplet wave (gotten from the ColorTab2Wave function) to, let's say, 256 rows, but couldn't get to the good result. I'm sure I am missing something simple.... any hint?

Thanks!

Nevermind, just realized that the single R, G, B waves can be interpolated separately....
