   Reykjavik Training Academy

   Colours are taken from the academy logo — glacier green, mint,
   and the deep navy of the wordmark. VATSIM Scandinavia's blue is
   kept as a supporting colour so the site still reads as part of
   the division.

   Flat design throughout: square corners, no gradients.
