Hi... I realized I uploaded the wrong photo. This is the columbine photo I meant to have loaded.  Ignore the other photo unless you are an expert in identifying native avens from non-native avens. :)  Do you know what might be causing the leaves to change color?  Thank again!

Thank you.. I think it is Stagonosporopsis aquilegiae because purple is involved even though the pictures in the handbook do not quite look like what I have. I have attached a few more photos. The leaves on many of the plants are completely purple on top, the stems are purple also , and the flowers have dried up without forming seeds it appears. On some there may be some powdery mildew are well.  I will remove the purpling plants and any mildew ones as well and dispose of them in my green waste garbage bin. Do I need to remove the roots in addition to the vegetative sections?  And I also have lupine in my garden and they have powdery mildew on their leaves and stems already - I normally get powdery mildew on the lupine every year but this is super early this year.   Should I likewise get rid of  the parts of the lupine that have mildew on them?  Thanks again.
