I like how you can get a ticket for using your phone while driving, so automakers decided to replace your tactile radio, where you don't need to look at it to operate, with what is basically a giant touchscreen phone in your car where you need to look at it to see what you're doing instead of feeling what you're doing.
I'm not aware of any other than what I've used in the past in post production and that's ColorChecker Passport Photo 2 by Calibrite ($119.) It's a software that helps you calibrate your monitor so that you can get your edits accurate for print. It also comes with a physical colorchecker that you can use as well for multiple lighting situations. Great tool for photographers that do a lot of post.
I'm sure there's some software out there that is more affordable or free that you can calibrate your monitor with.
How accurate are the palettes? Would we need to calibrate our monitors or does the site do that for you?
