Created attachment 167813 [details] A screenshot demonstrating text that is nearly invisible on the Color Grid sensor display SUMMARY Following recent software updates, the font color used in the "Color Grid" display style within the System Monitor GUI application exhibits extremely low contrast on bright-colored tiles. This issue significantly reduces readability, rendering the display style less effective for monitoring purposes. STEPS TO REPRODUCE 1. Launch the System Monitor GUI application. 2. Navigate to the left side panel and select the "Add New Page" option to create a new page. 3. On the newly added page, access the right configuration pane. Change the Display Style of the default "System Monitor Sensor" to "Color Grid". 4. Within the same configuration pane, under the "Sensors" section, navigate to CPUs -> [Group] CPU -> [Group] Total Usage (%) to select this specific sensor. 5. Observe the displayed results in the center pane, focusing on the contrast between the text and tile backgrounds. OBSERVED RESULT The font color on the tiles representing CPU usage appears excessively bright, especially on tiles with lighter backgrounds. This results in a significant reduction in contrast, making the text difficult to read (please see the attached file "wrong-contrast.png" for a visual representation of the issue). EXPECTED RESULT The application should maintain a high contrast ratio between text and tile backgrounds regardless of the tile's color, ensuring that text remains legible under all circumstances.
