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.
