Shades to avoid
■ PUMPKIN When seeking a pal for your purple scheme, earthy tones are the ones to shun. This feisty orange needs a much stronger partner and will squash lavender’s soft appeal.
■ Jet BLACK Certain to zap the loveliness from this sophisticated scheme, unforgiving black will look harsh and heavy-handed.
■ Custard As purple’s partner on the colour wheel, yellow should be a shoo-in – but this cloying version will make for a sickly effect. Want some sun? Pick a pastel instead.
