Change colors in green.css (link and title)

I feel stupid, but… In Customizr Theme, green skin, I would like to change color #9db6b8 (used for links and page title) with #519485, but I am unable to do that. I have tried to add it to customizr-child css, even changed all instances #9db668 in the original green.css in /wp-content/themes/customizr/inc/css/green.css, but the color #9db668 persists… Where is it defined? Thanks you
