Firefox and Safari both render colors using sRGB. Chrome isn't consistent. This can be forced through chrome://flags/#force-color-profile
and selecting sRGB.
When designing images, use View > Proof Setup > Monitor RGB
for an accurate rendering, ensure Edit > Color Settings
is on "North America General Purpose 2", and export images by ticking "Convert to sRGB" and deselecting "Embed Color Profile" (Chrome does not support image profiles).
