Change it up a bit and coordinate "Blue" with grey or brown. Any shade of grey. Any shade of brown. Years of designing with color have taught me I will always sell more baubles of blue than any other color.
How not to sell blue? When exhibiting a collection, always have Orange :). Orange sells blue! Yes, orange sells. There are those fashionistas that MUST have an accessory of orange. I've learned the orange offerings always increase the sales of blue. - ND
