[R] hex2RGB back to hex not the same?

Witness this oddity (to me):

> rainbow_hcl(10)[1]

[1] "#E18E9E"
> d <- attributes(hex2RGB(rainbow_hcl(10)))$coords[1,]
> rgb(d[1], d[2], d[3])
[1] "#C54D5F"

What happened? FYI, this came up as I'm trying to reuse the RGB values I get from rainbow_hcl in a call to rgb() where I can also set alpha transparency levels ...
