I would describe Timbleberry as a bright watermelon color, somewhere between a lighter/bright red and a dark pink. The first coat kind of goes on like a jelly, nice and even, and a little translucent. The second coat kind of a applies like a creme, with noticeable cuticle drag. I applied three coats to even out the second coat.
My home office is flooded with natural light and is great for taking pictures, however it has ugly blue walls and one day I will paint it. So until do, my photos have a blue cast reflecting back, just like in the photos above. I don't know why this happens on only some occasions and not all the time. My photo lamp is turned on as well which lessened the blue cast. Also the my camera is depicting timbleberry as more red than it really is, in real life. In real life it is more pink. Watermelon is the best way for me to describe this polish accurately.
Overall its an appropriate color for spring and summer. Its noticeable as well, a few people at work pointed out my nail polish to me. "Oh my gosh, you did your nails." "What color is that?" "Its really bright." Those are the statements I got.
Personally, its a color I'm okay with; I could take it or leave it.
UPDATE: 5/3/2012 Sinful Colors UK names this polish "thimbleberry, 108" same number. Looks like the same shade. http://www.sinfulcolors.co.uk/polishcolourchart.html
