Hi Fabrice,
You could define you own shades of gray (I believe there are at least
50) by adjusting the rgb values as I've shown below.
definecolor [ name = "verylightgray", r = 0.995, g = 0.995, b = 0.995 ] ;
definecolor [ name = "lightergray", r = 0.55, g = 0.55, b = 0.55 ] ;
draw lmt_shade [
path = (z0--z4--z5--z1--cycle),
direction = "left",
alternative = "linear",
colors = {"lightergray", "verylightgray"},
] xshifted 5cm;
I added it to your code after the lines:
draw z0--z4--z3--cycle;
draw z1--z5--z2--cycle;
draw rectangle;
Hope this helps.
Best Wishes
Keith

Hi,
Sorry for the late response. Thanks for the help. So I read the
documents and managed to get a gradient even if it's not exactly like
the figure.

While the luametafun (“Metafun XL”) manual is also (meta)fun, I meant
the general metafun(-s|-p) manual, the big one (>400 p. in the
“print”
version, >600 p. in the “screen” version). Recommended!
