Issue:
When the 'Over' allocation threshold is set to 0%, a resource that is allocated exactly the amount for the availability, it shows up as red (overallocated).

Steps to Reproduce
  1. Go to the Modern UX Staffing page.
  2. Check the default settings for the Allocation Threshold (by clicking in Modern UX Settings > Staffing). By default, Under allocation is definded as 30% and Over allocation is defined as 10%.
  3. While on the Resources to Investments view, check the cell background color for a resource that is allocated exactly the sum of his or her availability (e.g.: 5 days x 8 hours availability = 40.00 for a week). Background color is white, and will be for 0-30% under allocation and 0-10% over allocation.
  4. Change the settings to 0% for 'Under' allocation and 0% for 'Over' allocation.
Expected Results: Cell color is green for 39.99 hours, white for 40.00 and red for 40.01.
Actual Results: Cell color is green for 39.99, red for 40.00 and red for 40.01.
Resolution:
This behavior works as designed.

The number is inclusive to determine the color. 
When you set the over allocation value to 0% you will see the tool tip on hover over the first red square to the right of 100% in the heat map say 'Over Allocated 0-19%'. 
When you set the under allocation value to 0% you will see the tool tip on hover over the first green square to the left of 100% in the heat map say 'Under Allocated 0-19%'
If you set both under and over allocation percentages to 0%, the red color will be shown.
