Preventing Colour Changes?

[dancingsquirrel]

I'm creating illustrations from scratch on a transparent background, converting to png, and uploading. When I view my work on my laptop (Windows 10) its fine, but on my phone (Android) some of the colours are whack! Is this likely a problem with my phone settings specifically, or is everyone who sees my work on certain operating systems getting this?  Thanks friends!

If your work is saved in sRGB mode, then physically it will be the same between the devices. Might not be displayed the same Are are your images in Indexed mode?

Very probably differences in the display between computer and phone. What does your work look like in a Windows image viewer? Is it different from viewing in Gimp?

Gimp colour management by default is on. This can be turned off on an image basis from the view menu, the image menu or in the Edit -> Preferences menu. example https://i.imgur.com/1g3MQEU.jpg

AFAIK Windows viewer does not use color management - see: https://www.dpreview.com/forums/thread/4078572

Then is it all images or just your work? Get a third party image from somewhere. Look at it in Gimp. Look at it in Windows viewer Look at it in the android phone. What are the differences?

For past experience, computer monitor / display are set too bright. Not many users ever bother to change settings. Even more so for phones. Chances are your computer is less bright than your phone.

Then there is the image viewer. If using a web browser, most new browsers are color-managed. The exception is
the default Android Internet browser.

All sorts of things to consider.
