A light blue shirt with a navy suit creates a cool-toned palette ... for complementary tie colors like navy, brown, or dark red to balance the earthy tone. Deep forest or hunter green ties ...

UNIQLO and Finnish brand Marimekko are collaborating on another seasonal line this fall that includes lots of layering, shirts with nature motifs, and an autumnal Nordic color palette.

It's high time you went full Matisse with your T-shirt colors ... these tees give you serious color options, from fresh lilacs to bright teals to deep mauves and forest greens.
