Is This Disrespectful To Sororities & Fraternities?

Ok , so me and my cl leaders at my high school are trying to put together a sopre spirit week and the idea about a "College Day" came up and I'm curious to know would it be disrespectful to the Black Greek Letter Organization to wear colors that represent fraternities and sororities we were interested in pledging in college because there are alot of people in black greek fraternities and sororities on campus and I don't want to offend anybody?
