I just took an online class from the Altenew Academy. It was a good class and it only cost $7 and change-well worth it. One of the classes was Unexpected Color. This was a great exercise in stepping out of the box and I ended up loving a card that I thought I would hate.
The challenge is to use colors that break the rules. Put colors together that really don't "go together". Let me be clear about this. This is not a challenge to use colors you don't normally use because you don't like them. This means make a card with a color combo that breaks the rules of color coordination. The instructor used pink and orange with a touch of green. I went with aqua, red and lime green. Be brave!!!! Once I got over the initial feeling of ewwww, I grew to like the combo and had fun making the card. I even got so brave as to highlight the flowers in black and white instead of the natural shades of red that I should have used. I can't wait to see what you come up with.
