The most adorable, sweetest boy in the world is asking you to wear yellow.

A 5-year-old boy named Seth Lane, from Corby, Northamptonshire has been living half of his life with a severe immunodeficiency. So, he has made a touching video asking people to wear yellow to support him during his second bone marrow transplant.

The first bone marrow transplant was unsuccessful, according to itv.com.

Yellow is his favorite color and he is asking you to wear it on March 27th.

You can post your picture on Facebook, Twitter, or Instagram using #wearyellowforseth. His parents promise to print the pictures and place them in Seth's room so he can see all of his supporters.

I know I'll be wearing yellow! Let's go Seth!
