>I could swear I've done this before, but no matter what I do, I cannot seem to change the Header ForeColor of each Column to Blue from the default of Black.So, how do you do this? I've tried it at the control level (Text), and even the Column itself. No change whatsoever. Why then are the properties there in each case, yet the color does not change? Okay, what did this old guy miss? (Where are my glasses?...)

You can only do this when Themes property of the form/grid is set to false. By default you're not allowed to change them as it's controlled by the current theme.
