red vs black

Hi All,

I’m very new at this whole “early education” thing, so please excuse my ignorance… (frankly, I’ve never been in a “forum” either, so I have no idea if I’m even starting a discussion correctly! - forgive me if this shows up somewhere it’s not supposed to be - and, please correct me!)

I’m currently using the YBCR dvd program (3 weeks today) and stumbled across BrillKids last week. Here’s my question…why is it red and not black print for flashcards? The YBCR videos use different colours, fonts & backgrounds. On several of the threads that I’ve read red ink is encouraged to be used on white background. I’d like to know why? Is this only for younger babies (mine is 14months)? Is it okay to use black? I know that Glenn Doman suggests red, but WHY???

Thanks so much!
