Kaley Cuoco-Sweeting goes pretty in pink -- pink hair, that is

First pixie, then pink! Kaley Cuoco-Sweeting has gone pastel.

"The Big Bang Theory" star debuted a pink hair dye job on her Instagram account on Tuesday, touting the latest color craze to hit Hollywood. (Blond stars including Nicole Richie, Hilary Duff and Julianne Hough have recently experimented with cotton candy-colored mantles.)

"Have wanted to do this for years! Finally went pretty in pink!" the former blond wrote on the account named after her dog, thanking her colorist for the giving her "such a special color!"

"Obsessed!" and "#doyou," she added.

The 29-year-old fully embraced the hue by Wednesday and shared a timely rose-filtered snapshot that she captioned "pink obsessed."

Pink obsessed this morning :) ¿¿¿¿¿¿¿¿ @vspaeth

Remember, this is the same girl who wore a petal pink Vera Wang gown when she and tennis player Ryan Sweeting tied the knot in January 2013.

Her colorist also posted a photo collage and responded with "The prettiest in pink @normancook #killingit #shemademedoit #looksamazing #duh"

Cuoco-Sweeting, 29, made hair headlines last June when she chopped off her long blond tresses for a pixie cut. The dramatic move, which came just after she test-drove a long bob, ended up being written into her highly rated CBS comedy.

Does Kaley make you think pink too? Tell us in comments.
