Final answer:
When applying color to new growth, overlapping can result in uneven color.
Step-by-step explanation:
When applying color to new growth, overlapping can result in a line of:
- Uneven color
- Straight color
- Blended color
- No color
Overlapping can cause uneven color because the color from the previous application can mix with the new color, creating a visible line where the two colors meet.
