Why does the color of my website comes up differently on other Macs?

How can it be, that the green color I’am using on my website looks differently on a different Mac? I used the ‘Digital Color Meter’ to always have the same color. On my Mac and several other devices it shows up fine. The Mac where it does not show the right color runs with: macOS Sierra, Version 10.12.6, Graphiccard AMD Radeon R9 M380 2048 MB

I add a screen shot where you can see the different greens:

Thanks a lot for any idea you have, c.

Hello @Carola

I’m no expert on this …

But I wonder if it has to do with the Colour Profile that is embedded in your png with the logo (fanpost-299.png)

Colour Profile: sRGB IEC61966-2.1

A long time ago I had a similar problem, and if I remember correctly, it was because of an embedded colour profile.

Maybe this Mac interprets this Colour Profile differently?
But why? I don’t know …

Sorry I can’t help you more … I hope someone has the solution!
