A pair of what I take to be coal tits turned up in the back garden this morning, with distinctive black markings on the heads and bellies about the gold ochre on the chart left.

Google seems a bit vague on belly colour with suggestions varying from yellow through buff to a pale mauve, aka gold ochre.

While I think that buff is what this chart calls yellow ochre. See the Kent Buffs.

Which all goes to show that naming colours in any kind of detail is a tricky business.
