SUBMIT: Your Most Vibrant Color Photo by October 24th. WIN: Color Splash Studio for Mac [Closed]

Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.

Submit your best shot to our weekly competition for a chance to win an awesome prize. Phoneographers only—both Android and iPhone welcome! Check it out now.

This week's Giveaway Tuesday Photo Challenge is for Mac users with an eye for vivid color. Dig up and submit your most vibrant colored photograph, whether it's awash in a single monochrome, takes advantage of complimentary colors, or draws attention to the subject by using selective colors—it doesn't matter, as long as it utilizes color as the most striking element of the image.

You can use a photo from any device—manual, digital camera or smartphone—along with any software or filter app to create colorful effects. Below are a few examples of images that would be applicable submissions.

This photo by flickr user sarsifa makes good use of complimentary colors:

ENTER TO WIN

Good news! This week we will choose five lucky winners, and what's more, each winner will receive 5 copies of MacPhun's Color Splash Studio, normally available in the Mac App Store for $9.99 each. With 5 copies, you and four of your friends can start playing with your photos using selective colors.

Color Splash Studio lets you work with practically all image types up to 32 megapixels resolution, even RAW formats. You can also share your finished photo with most popular social networks.

I'm a novice when it comes to making monochromatic images, but in just a few minutes I got the hang of it. Below is my first go at it. Pretty good for just a couple minutes.

You can keep up to date on Color Splash Studio and more of MacPhun's photo apps on Twitter, as well as check out some Color Splash user pics on Flickr. And remember, this app is for Mac only. Each winner will receive a link to download the program, along with five codes.
