Yes Irish Halo is really that green.
Fringy is very green also especially early morning. The picture of Fringy was actually the last flower that was on a rebloom scape on a very hot day. It has more green and more base color which is a soft peach color, on cooler days. Fringy was a huge fan when I got it in 2009, it bloomed over and over again and was the last flower blooming for me that year.
You can't beat Last Snowflake which has quite a bit of green on the edges early morning, which lightens as the day progresses. It blooms very late and has been gorgeous every year since I got it in 2007. It has a special place on top of an old tree stump in the back year.
