[Bug]: Graphite-Mono text tends to be black

[Cruleo]

Bug Report

Description

When the QT6CT selected theme is Kvantum > Custom Palette > Color scheme: Graphite Mono, it leads to some text being black (see picture below).

If the Palette in QT6CT is set to Default, then text is behaving as expected.

Additionally, the sidebar on Dolphin color of text and selected colour seems to be overlapping (shown below). If I double click the entry on the sidebar, then text shows as expected.

Both of the listed issues do not occur with Graphite-Rimless-dark from here.

Steps to Reproduce

1. Use Graphite-Mono theme
2. Open Dolphin
3. Click on "Places" sidebar
4. Open Qt6Ct or Kvantum Manager
5. See some text being dark (especially hover tooltips)

Expected Behavior

Dolphin sidebar text should be readable. Tooltips having black text should follow the text colour of normal text.

Environment
