Little known fact, but Pantone choose a ‘Color for the Year‘ and for 2018 it is Ultra Violet. If you follow that link and scroll down you’ll also find the previous year’s colours.
What is great about this is they also suggest very useful colour combinations in their Tools for Designers, organised by mood. Allowing everyone to be ‘on trend’ this year.
Colours change with the seasons and also over the years to reflect fashion, global design influences and the idea of what feels ‘modern’ and ‘classic.
