Today is Autism Awareness Day! In honor of that, many businesses, landmarks, and homes around the world are lighting up blue.

We thought it would be cool to share some ways you can participate in spreading awareness for autism. So, here are a few ways to show support:

1 Change outdoor or indoor white bulbs to blue bulbs.

2 Tint windows with blue gel sheets

3 Cover existing fixtures with blue gel filters

4 Post your photos on Facebook, Twitter, Google+, Instagram, or Flickr with the hashtag #LIUB to be a part of the global autism awareness movement!

5 Turn your Facebook or Twitter profile picture blue

6 Tweet autism facts with the hashtag LIUB

7 Ask family, friends, coworkers, and staff to wear blue (ties, scarfs, shirts, etc.)

8 Supply Autism Speaks lapel pins, bracelets, or other blue accessories to wear during the month of April.
