Organizations seeking to promote awareness about this affliction are asking folks to wear blue and green as a sign of their being in solidarity with the plight of one's who have NF.
Additionally, buildings across the globe are turning on blue and green lights to to show their support; as evidenced in a posting by the Children's Tumor Foundation @ https://www.ctf.org/shine-a-light-on-nf/
Unfortunately, even though I have been traumatized by many consequences related to my having NF, I don't own blue and green clothing, so I cannot help in this manner, but what I am doing to raise awareness is working on a book which is tentatively titled, Imperfect Strangers, and its content describes some of the consequences of living with NF.
A video about "Imperfect Strangers" can be found within my Vimeo and You Tube channels. Here are the links:

And while I may not be wearing blue and green clothing, the European starlings who visit my garden, have blue and green features, as evidenced by the photos I'm including here in the images below:
This bird type is featured (along with many other bird varieties) in my books. You can find info re this matter within a post on my blog via this link:
