Option 1: Fill without formatting
Select the cells.
Press Ctrl + D.
Click the small Auto Fill Options icon.
Choose Fill Without Formatting.
This keeps all existing cell colors exactly as they are.
Option 2: Paste values only If you don’t need formulas:
Ctrl + C
Select target cells
Ctrl + Alt + V → V → Enter
Only text is pasted — no color.
Option 3: Use formulas instead of Ctrl + D If you’re copying from the cell above:
=A1
Fill down — formulas never copy formatting.
Long-term solution (if colors should be consistent)
Use Conditional Formatting instead of manual fills:
Select the range.
Home → Conditional Formatting.
Define your color rules.
This prevents Ctrl + D from “breaking” colors because formatting is rule-based.
