‘vivid’, ‘brilliant’, ‘strong’, ‘deep’, ‘light’, ‘dark’ and ‘pale’.
su -ish
A very old suffix first used in the description of origins such as ‘Pictish’. Also
used to mean ‘resembling’ as in ‘childish’. The suffix is now used with adjectives
(particularly colours) to indicate the quality of being ‘somewhat’, ‘nearly’ or ‘slightly’
as in ‘reddish’ and ‘bluish’. Some colours are capable of bearing this suffix including
black, white, pink, red, brown, yellow, green, blue, grey, ochre and purple, but
not orange, gold, silver, or olive or many other colours. Fielding refers to ‘duskish’
and Albers to ‘violetish’.
