Thanks Lindy.
I remain confused. On one hand your UX designer says it depends on the theme, and on the other he intimates that the difference is set your end.
Here’s the theme I’ve applied:
{"sidebarBg":"#00B0A0","sidebarText":"#fff","sidebarUnreadText":"#fff","sidebarTextHoverBg":"#136197","sidebarTextActiveBorder":"#FEC019","sidebarTextActiveColor":"#FFFFFF","sidebarHeaderBg":"#404040","sidebarHeaderTextColor":"#FFFFFF","onlineIndicator":"#7DBE00","awayIndicator":"#DCBD4E","mentionBj":"#FBFBFB","mentionColor":"#2071A7","centerChannelBg":"#f2f4f8","centerChannelColor":"#333333","newMessageSeparator":"#FF8800","linkColor":"#2f81b7","buttonBg":"#1dacfc","buttonColor":"#FFFFFF","errorTextColor":"#a94442","mentionHighlightBg":"#f3e197","mentionHighlightLink":"#2f81b7","codeTheme":"github"}
As you can see, there is no opacity. The distinction between font color and background couldn’t be clearer. But as soon as Mattermost applies 60%, the contrast fails WCAG 2.0. I agree that themes must distinguish inactive and unread items, but this clearly is not then the way to do it.
This is unacceptable and we need to fix it. Our application of Mattermost in particular is aimed at a community that values digital inclusion, encompassing accessibility.
Thanks in advance for your consideration.
