Color is certainly subjective. I find it interesting in the Flora of China, not sure if it is a translation issue or not, that pink flower color is invariably listed as "pale red". Going back to
Antennaria, for most of the deeper color forms of
A. rosea and
A. dioica (including the nice one you show Trond) I would call them pink; a nice bright or rich pink, but definitely pink. There are some selections that, repeating my previous characterization, "approach" red.
I think the genus Penstemon has some interesting cases, such as with the shrubby Dasanthera species, where flower color traverses the pink to red spectrum. I hear people describe the flowers on
Penstemon rupicola as red, or "cherry red", but to me they are definitely a rich pink.
http://calphotos.berkeley.edu/cgi/img_query?enlarge=0000+0000+0809+1902Penstemon newberryi has several forms, often the flowers are a rich intense pink, or "rose-red", but there are some true pure red flowered forms. Bob Nold's book on Penstemon mentions a cultivar of
P. newberryi named
'Red Lassen' offered by Siskiyou Rare Plant Nursery; a cherry red selection. I once grew a form of
Penstemon newberryi ssp. sonomensis from seed that had amazing blood red flowers, not pink in the slightest. Googling around, I found another cultivar at Yerba Buena Nursery named
Penstemon newberryi sonomensis 'St. Helena'.

Penstemon newberryi ssp. sonomensis, they look decidedly red. The subspecies is notoriously fussy in cultivation, but who wouldn't want to grow this beauty.
