Jonah Lehrer sug­gests that the ideal cre­ative work­place is “a room with blue walls that feels very far away and is filled with ref­er­ences to for­eign coun­tries”. Why would these three con­di­tions be con­ducive to creativity?

Colours can influ­ence how we think (in one exper­i­ment, red back­grounds were found to make par­tic­i­pants more accu­rate, while blue back­grounds drew out creativity).

The link­age of red and accu­racy makes some intu­itive sense, since peo­ple tend to asso­ciate red (stop signs, the color of blood, etc.) with dan­ger and cau­tion. But why would blue make us more cre­ative? […] It turns out moments of cre­ative insight are best achieved when peo­ple are in a relaxed, peace­ful state of mind.

Psy­cho­log­i­cal dis­tance (think­ing some­thing is fur­ther away) makes us more likely to solve dif­fi­cult prob­lems cre­atively.

Accord­ing to [con­strual level the­ory (CLT)], psy­cho­log­i­cal dis­tance affects the way we men­tally rep­re­sent things, so that dis­tant things are rep­re­sented in a rel­a­tively abstract way while psy­cho­log­i­cally near things seem more con­crete. […] Abstract think­ing makes it eas­ier for peo­ple to form sur­pris­ing con­nec­tions between seem­ingly unre­lated concepts.

Liv­ing abroad increases cre­ativ­ity (pre­vi­ously).

First, liv­ing abroad can allow indi­vid­u­als access to a greater num­ber of novel ideas and con­cepts, which can then act as inputs for the cre­ative process. Sec­ond, liv­ing abroad may allow peo­ple to approach prob­lems from dif­fer­ent per­spec­tives. […] Third, expe­ri­ences in for­eign cul­tures can increase the psy­cho­log­i­cal readi­ness to accept and recruit ideas from unfa­mil­iar sources, thus facil­i­tat­ing the processes of uncon­scious idea recombination.
