I think I detected what was causing the issue, the background map, when I remove it the color I choose loads just fine. I think I’ll keep the map removed. Thanks anyway for your help.
Thanks for your reply, no caching plugin installed on my site yet and I changed the right position of my contact page on the customizer. I did try with other pages and it’s working fine, the issue is located only in contact page. The new color I choose loads for 1 second and then the old color take over the page.
