For my coloring I started with the rainbow and made long streaks while ignored everything else in the water. I wanted a really bright look and knew that after I added blue things would get muted a little so I made sure to use brighter, more neon colors. After adding the blue streaks, I then colored the rest of the image.
For the sand I tried to go for the bright white that is sometimes seen in the shallow tropical waters - you know, the paradise kind of water that is crystal clear and almost looks like glass. Yeaah... that's where I wanted to be. :D I used E44, E43, E42, E41, and E40 but stayed more towards the lighter colors. Then I used bright colors again for the coral, seashells, fish and everything.
The last thing I did was use my white gel pen and color in the bubbles to make them stand out a little more. The image actually didn't take that long to color, maybe 30 minutes, and by starting with the rainbow I felt I could toss it out if needed without wasting too much effort. However, it didn't turn out so bad so I didn't need to start over. :D
That's about it for the rainbow challenge. You should give it a try with your next water project! Thanks for dropping by and I hop you've been a little inspired today. *Hugs
