Can I dye the ends of my hair with k-tip extensions?

I have k-tip extensions (Priscilla Valles brand) and medium/dark brown hair. I wanted to dye just the tips of my hair either a mint green or teal color, but I'm not sure if this is possible without bleaching first. I am getting my extensions redone in two weeks so I'm not really worried about long-term issues, since I'll be getting new ones put in and was just planning to cut off the ends of my hair that I dye. I just want to make sure this won't completely ruin the look of my extensions if I color them. Also looking for suggestions on what dyes could work well.
