In a 6.2.10.6 Portal instance I switched on the Classic Theme and choose the "Dark" color scheme. However, the dark color scheme has some portions of the UI that are difficult to read (see screenshots of "hard-to-read-labels.png, hard-to-read-errors.png").

Steps to reproduce

• on default home page add a new page and choose blogs template.
• for new page using the blogs template switch the look and feel to use Classic > Dark color scheme
• notice that the field labels are too dark and the fields themselves (text inputs text areas, ckeditor) are too bright and those colors still need to be inverted
