test bug4314194 mentioned in [JDK-8298083](https://bugs.openjdk.org/browse/JDK-8298083) fails in GTK LAF and rightly it is problemlisted for linux machine. @mrserb has created a bug [JDK-8298153](https://bugs.openjdk.org/browse/JDK-8298153).

So, I think we need to check if color is set by user explicitly in GTK LAF.
