Lovely Aquilegia. The first does look much like your native Aquilegia caerulea, the Colorado state flower. The yellow is my favorite. Aquilegia canadensis,, orange and yellow, is the one I grew up seeing quite commonly in open woods. They hybridize and self sow easily, so watch for new color combinations popping up wherever you grow 2 or more types together.
A columbine for Columbine does seem an appropriate remembrance.
