Get consistent colours across devices
Use colour profiles to make sure the colours in your images appear the same on all your displays—and when you print.
Find colour values
Use the Calculator to get the values for a colour on your screen—right down to the pixel. You can also get the values for a colour in another installed colour profile to make sure the colour appears the same on all your devices, including printers.
