Talking about the main color trends for 2019 spotted at Milan Design Week 2018, there were two main trends in my opinion to note this year: first one is the use of bold colors and the second one is the pastel colors or in color combinations such as rainbow patterns or gradients.  

The 2019 color choices are as follows:

1.  Yellow
2.  Neo-Mint
3.  IKB - international klein blue
4.  Mango
 

In 2018, the color choices were:

1.  Millenial Pink
2.  Mustard Yellow
3.  Burgundy Red
