Dashboard colourpicker to HTTP response

[Zappbranningan]

Hi, I'm new to node red.
I want to get an RGB value from colour picker with a 'HTTP in' and a 'HTTP response'.
I made the following flow:

The 'change' node is set as follows

So when I change the value with the colour picker:
I get the value stored in 'flow'
But when I start the GET from my browser or my STM32, I get empty {}
After the operation, the flow is also empty:
I tried looking in the forum, but I couldn't find the right way to do it (probably my question is mach to easy).

Thanks in advance!
