Hello @LBC_Emily.
I appreciate your patience in this matter. I'm here to show you how to fix this issue with QuickBooks Desktop's Icon bar.
Let's change the preferences from the Desktop view. This way, we can change its color preference.
1. Go to Edit and select Preference.
2. Click the Desktop View, then tick the check box on the Switch to colored icons/light background on the Top Icon Bar.
After that, you can return them to their original form.
I've also provided a link where you can refer to while working with us: Help Articles for QuickBooks Desktop.
Get back to us if you still need further assistance with your Desktop preferences. I'm always here to back you up.
