I really like it and love the outside border - it really completes the design. Are you just naming it for yourself or doing it for a competition?
I looked on the Eleanor Burns site at
Kaleidoscope 2
https://www.quiltinaday.com/shoponline/book/193932
and half way down the page is a Purple, blue and green quilt which is very close (different arrangement of lights and darks but the same sense imho) . You could always call it
Kaleidoscope 2 Variation or some such concoction of words but I did not find any that looked exactly like what you have created even on Pintrest Maybe someone else will find something.
