Why is the color of the same image different when displayed on laptop and mobile device
I have created a banner with a pink background (so I thought) on my laptop. When I viewed the same image on my tablet and mobile phone the background was yellowish. My laptop runs Windows 8.1 where the Windows color system device profile is sRGB IEC61966-2.1. My tablet is a galaxy tab s and mobile phone is galaxy s4.
Okay, so here is the thing I've learned from working in a room filled with screens from the same brand:
No two screens are usually identical, when it comes to color.
Normally, you'd have to adjust your screen colors manually, to get the "right" colors. Your average user will probably use the default settings and the ones who do choose to calibrate will typically do so with different settings, so one with a higher brightness, the other with less saturation, and so on
Such is also the case on other devices. Usually, you won't get the exact same result you were seeing while designing, being perfectly the same on all other devices.
