@dmick1954 - Sure, try this:
.titlebar-inner {
color: #ffffff;
}
Note - this will also change the color of the backward/forward arrows on the left side of the titlebar. If you don’t want those changed, you’ll have to target each button separately.
Edit - I should add that some themes, including the defaults, usually show these as fainter until you hover over them. This might make that action a little less pronounced. It’s possible to affect the hover status as well, but it’s a bit more complicated.
Also, if in the end you want them to be the same, you can shorten your code a bit by combining both of these snippets into one:
.titlebar-text, .titlebar-inner {
color: #ffffff;
}
