This firework has gone red!

She may be occupied with her California Dreams tour, but that doesn't mean Katy Perry is too busy for a major hair color upgrade — she just traded her black tresses for newly dyed crimson locks!

Perry, 26, showed off her fiery new hue in Miami while sporting a polka dot baby pink bikini poolside on Tuesday.

Just last week the "E.T." singer hinted via Twitter about switching up her hair color: "Tonight I dye my hair a different color. Can you guess which color?" she asked her followers June 16.

The next day, she tweeted, "So I didn't get to the exact color I wanted from being black for so long! To get to goal I have to be a ginger for three weeks!"

"If I don't wait three weeks, I'll end up with no hair or a pixie '90s cut with a barette in the front. It's okay, I'll get to my secret color(s) soon!" said her following tweet.

No word what Perry's "secret color" is, but it's nice to see her lightening up a bit for summer.
