Faxing in Colour?

I recently received a fax and in it there was a sentence that says “The words in BLUE are the changes made on ...……” hmmm…. That really got me wondering if there are newer fax technologies in the market that faxes & prints in colour? (as my fax machine faxes, receives & prints only in Black & White, maybe I am a bit outdated. Print maybe, but faxing & receiving in colour?)
