Does anyone know, how to change values the frame colors of the meters shown in the screenshot (also their color values) from white to black oder another dark color? I just started using Windows 7 & find the contrast too low. I can´t find more detailed information in the status bar codes section.

Currently is use this code:
{h!L} <#ff0000> {hiL} </#>{h!L}
{h!L} {smp3L} /{h!L}{h!L} {tmp3L} {h!L}
{i:dir} {sdL}/{tdL}
{i:.txt} {sfL}/{tfL}
{sbLa} von {tbLa}
