Make Text in Chart Tabs more visible

With more than one Tab on a chart (ie: each Tab for a different instrument or time period) I can only see the text (instrument and contract name) for the chart that’s open. The others are almost grayed out against a gray background. Perhaps have the text become visible when hovering the cursor over them at least (?)

As is I have to click on the Tab, hence open/select the chart, to know which it is.

Many Thx
