I know Gareth has made changes to the dimming of hidden resources and hidden courses in the breadcrumbs. For us these changes have made things worse as we use very similar gray colours as our default theme colour. Now hidden courses in the breadcrumb are almost unreadable and hidden resource text is the same as non-hidden resources/activities which will send our teachers into a spin (even though the icon is dimmed) if we run with this in a live system. I had a look at some of the fixes #60 and #629 and in the theme files I changed the variables.less colour for @grayLight but changing this didn't make any difference. I get lost in all the github stuff as I am not a coder.
So what I need help with is how to change the colour of hidden resources/activities on the course page and also in the breadcrumb menu (hidden course names). Where in the code for essential do I do this? And more importantly exactly what do I change it to if I want a much lighter shade of gray.
