I love color challenges and played along with one from Split Coast Stampers.
I used the stamp set Flutter By from Lawn Fawn. The ink colors are Mango Melody, Poppy Parade, and Call Me Clover, all SU colors. I used these colors with a blender pen. This is the first time I used this stamp set. It is a nice set with a lot of possibilities, so you will see it again hopefully soon.
I will be posting this on Simon Says Stamp blog with the Anything Goes challenge: https://www.simonsaysstampblog.com/wednesdaychallenge/simon-says-anything-goes-62/

Love the colors!
Thank you Diana. I like how bright they are.
I wish I loved color challenges,you rocked this one.
It helps if you own the exact colors or have a close match. Mom had many SU colors in the marker form, and I brought quite a few markers home.
The colors are really pretty and you met the challenge perfectly.
Great card for the challenge and the colours are wonderfully bright and cheery.
Very nicely done! The butterfly is gorgeous with those pretty flowers.
Very beautiful CAS card
Thank you, Gerry. I enjoyed masking and coloring these images.
Beautiful card, your flowers are so pretty.
Thank you for joining us at Simon Says Stamp Wednesday Challenge this week.
