Doesn't that raise the question about what the red pigmentation does
(assuming all other mulch properties are identical)? Is it the reflected
red light back to the plant that makes a difference or is it a change in the
ground temperature under it?

Red mulch under tomato plants will increase yield, could colour of
benches, shade cloth and walls help our orchids? I have painted surfaces
white for total light intensity but could there be a colour that would be
an improvement?
