Hi there! I understand that you're having some trouble tapping on a color choice because of a bar obstructing the row in the Happy Color app. Let's see if we can get this sorted out.

To start, could you let me know if this issue started after a specific update, or has it been happening for a while? Also, please confirm if the bar you’re seeing is a permanent UI element, or does it appear under certain conditions, like when you select something?

In the meantime, here's a general approach we can try to address the issue:

1. Restart the App: Close the Happy Color app completely (make sure it’s not running in the background) and then reopen it. Sometimes, a simple restart can resolve display issues.

2. Update the App: Ensure that you're using the latest version of Happy Color. Go to the Google Play Store, search for Happy Color, and see if there’s an update available. Installing the latest version can often fix bugs or glitches.

3. Check for UI Settings: In the app settings, see if there's an option related to UI or display mode. Sometimes changing these settings can resolve display issues.

4. Clear Cache: You can try clearing the cache for the Happy Color app. Go to your device’s Settings > Apps > Happy Color > Storage > Clear Cache. This can help if the app's temporary files are causing the issue.

5. Reinstall the App: If none of the above steps work, you might consider uninstalling and then reinstalling the app. This often resolves persistent issues by providing a fresh version of the app.

Let me know how these steps go, and if the problem continues, we can explore some more advanced troubleshooting methods together!
