Confused about cervix colour???

So i had my 6 month smear and colposcopy today due to previously having a cone excision to remove CIN3 and high risk hpv positive found at my last colposcopy. I had more biopsies taken today. The doctor said they are confused about the colour of my cervix and its rare. So they wanted to take two punch biopsies. I didnt think as to ask what this means i just wanted to get out as its my 3rd colposcopy within a year. Im worried now does anyone know what this could mean? Thank you x
