I think most designers have some tool they always reach out for - a certain shape you always like, a favourite, time-tested font that never fails to work or a format you just like to work with. For me it's a colour. I keep going back to this orange vermillion colour, which happens to be the colour of San Francisco's Golden Gate Bridge. I don't know who gave it the odd name International Orange, but that's the official name.
Initially it was selected to by architect Irving Morrow to complement the natural surroundings and enhance visibility in the SF fog. Don't know about visibility in fog, but I have found to to be a very pleasant and timeless colour that adds warmth to any room, be it a restaurant, a home or a setting.
The closest existing colour codes to the Golden Gate Bridge International Orange are
PMS 173 (CYMK = 0%, 80%, 94%, 1%),
PMS 174 (CYMK 8%, 85%, 100%, 34%)
Pantone 180 (CYMK 19.4%, 77.9%, 79.6%, 3.6%)
Alternatively, put some flowers in your hair and go match the samples in San Francisco. Be careful not to leave your heart there, though.
