If you want a definition of pastel, I guess you could say something
technical like hue (pure color) plus white equals tint (which is the more
appropriate term for 'pastel', although probably not as understood in common
usage) -- that's reaching back to first year color theory. You could then
specify that the value be equal or above 'x' (whatever/on the light end) on
a gray scale from 1-10 (ends being white and black). I've never actually
seen any guidelines read that way, though. And it would mean that staff or
the commission (whoever would determine compliance) would understand the
definitions of 'value' and so forth and how to compare colors against such a
scale. Some people really have difficulty doing this. Oh wait -- here's
'tint' from theWebster's: "a variation of a color produced by adding white
to it and characterized by a low saturation with relatively high lightness."
The definition for 'pastel' is much more vague (not good for guidelines when
you're trying to be specific): "any of various pale or light colors".
If it is pure tint that is required (vs. a shade -- hue plus black, or a
tone -- hue plus grey), the above might work, but it would probably be
off-putting to owners or contractors just because of the language. If your
guidelines have a section for definitions, you'd have to define 'tint',
'saturation', 'lightness' and so forth. Is there a reason not to just go
out with one manufacturer's paint wheel and get some paint colors from
existing acceptable color schemes to use as examples for the general public
and the commission? From my own experience (not writing guidelines, just
observing how people choose to paint their houses), you've really got to
watch the 'saturation' as well. What might look 'lighter' than a pure hue
on a paint chip can be really hideously bright.
Good luck!
