"Can you get these colors," Terry, essentially asked my cousin Rosaleen Salvo in Florida this week. 
She sent a photo of an ice cave beneath a glacier. I've tried painting ice bergs before, with no luck, but...
I had been stuck, but the chance to play with color helped me get started. The first day I just played with some Peacock Blue, some turquoise, some green and a touch or two more of other blues. I also Googled a lot of photos of ice caves, looking for ideas for a composition.
Finally today, I just went for it, painting quickly, blending colors, hoping for transparency and light to catch the magic luminosity of those caves.
The first one was a little too uptight, and the second one much quicker.
I'm not sure I've captured them yet, but I'm close, and I got to have fun with my favorite colors...blues. Which do you prefer?
Thanks for the challenge, cousin. I'll try again.
