Affinity designer V1. Colour issue can't select the shade of blue I used previously

[Paul240z]

Hope I can explain this correctly -
 

So I made a design in affinity a while back and wanted to use the exact same shade of vivid blue I had used in this old design.
 

So I start my new project and I use the colour pick tool to capture the vivid blue colour code from the old design, but when I paste it into the colour code on the new design it looks purple and muted.
 

Both the old and new designs are RGB8 what am I doing wrong? 
 

Hope someone can help, it's driving me crazy 🙂
 

Many thanks
Paul

Which “colour pick tool” are you using.
There’s one on the Tools bar, there’s another in the Swatches Panel, one in the Colour Panel, and various others in various dialogs/pop-ups.

Also, from what I remember, you don’t “paste” anything with any of these tools so what are you doing, exactly?

If you can supply a full-screen video showing what you are doing and what you are doing it with/to then that would help.

Also, do your old and new documents use the same color format and color profile?
