Are there any good free ones out there?

Free or expensive, they all work the same. The apps and programs use a very small color space called sRGB. It displays only a fraction of the colors we see in real life. And to make matters worse, the colors you see from a device or computer monitor are comprised of wavelengths of light that's beamed to your eyeballs. Paint color in real life is reflected wavelengths to your eyeballs. Two completely different visual sensations - one absolutely can not mimic the other accurately.

So, if you're struggling with color choices for you kitchen, the apps and programs aren't going to help unless you want to use them to simply search for color names or inspirational photos.

Thanks for that info Lori.

So outside of hiring an interior designer, I'm best to stick with making a few best guesses and trying sample pots!

SW Colorsnap Visualizer. I use it just to get an idea of the color I want. Just don't go in and purchase that specific color by name, it is never the same (as Lori mentions above).

Please, always look at proper paint swatches in person! Colours on the sites, in magazines are never truly accurate. Just use them for general colour concepts- then go old school.
