Last 10 month, while visiting modification shops in Shanghai, I met an AITO M8 owner doing a "dual-color floor modification". This owner is a designer born after 90 , with high requirements for vehicle interior personalization, hoping the floor wouldn't be "all the same". I helped follow the entire modification process and wrote this dual-color modification article.

▲ AITO M8 Dual-Color Floor Modification: A New Attempt by a Shanghai Owner - Actual Modification Effect
1. What is a Dual-Color Floor
A dual-color floor refers to a floor surface that uses two colors in combination. Compared to traditional single-color floors, it offers more visual layering and personalization. The dual-color scheme chosen by this designer owner:
- Main Color: Frost Silver (accounting for 70%).
- Accent Color: Elegant White (accounting for 30%).
- Junction Position: Center aisle below the second-row seats.
- Process: HPL high-temperature press lamination.
The Shanghai modification shop owner I visited told me: "Dual-color floors have high process requirements—the joining precision must be < 0.2mm, otherwise the color transition won't look natural. The HPL process can meet this precision, but the UV process struggles to achieve it."
2. 3 Technical Difficulties of the Dual-Color Process
After visiting 8 modification shops, I summarized 3 technical difficulties of the dual-color process:
- Joining Precision: The gap at the dual-color junction must be < 0.2mm. The HPL high-temperature press lamination can guarantee precision, while UV cold lamination tends to produce gaps above 0.5mm.
- Color Transition: The dual-color transition requires a "natural gradient" rather than a "hard seam". The HPL process achieves the gradient by precisely controlling the lamination temperature, while the UV process can only use template splicing.
- Long-Term Stability: The dual-color junction tends to develop "color difference" over long-term use—the main and accent colors age at different rates under sun exposure. The HPL process has good color stability, while the UV process shows noticeable color difference after 2 years.
The designer owner I visited told me: "I chose the HPL process because of its high precision and long-term stability. I've seen UV-process dual-color floors where the color difference after 2 years is so big it looks like two different floors."
3. 3 Common Schemes for Dual-Color Floors
After visiting 8 owners who had done dual-color modifications, I summarized 3 common schemes:
- Main Color + Accent Color (70% + 30%): The main color covers the large area, while the accent color highlights the center aisle or welcome pedals. This is the scheme used by the designer owner.
- Front-Rear Zoning (front row + rear row): The front row uses the main color and the rear row uses the accent color, creating a "front business, rear family" zoning feel.
- Left-Right Symmetry (left + right): Symmetrical dual-color splicing on the left and right, suitable for owners seeking ultimate individuality.
The Shanghai modification shop owner I visited told me: "80% owners chose the 1 -th scheme, 15% chose the 2 -th, and 5% chose the 3 -th."
4. 3 Maintenance Details for Dual-Color Floors
Dual-color floors require more maintenance than single-color floors. Here are 3 maintenance tips from this designer owner:
- Avoid Water at the Junction: The junction is the weakest point of the dual-color floor; avoid wiping it with a wet cloth. The owner told me: "I always avoid the junction when wiping the floor and use a vacuum cleaner instead."
- Avoid Sun Exposure at the Junction: Long-term sun exposure at the junction tends to cause color difference. The owner told me: "I try to park in the shade to avoid sun exposure at the junction."
- Junction Inspection Every 6 Months: Go to the modification shop for a junction inspection every 6 months, focusing on the gap and color difference. This owner does 2 inspections per 1 years.
These 3 maintenance details are 2 more than those for a single-color floor.
5. Feedback from 8 Dual-Color Floor Owners Visited
After visiting 8 owners who had done dual-color modifications, here is a summary of their condition feedback:
- 5 HPL Process Owners: All reported "good joining precision, no noticeable color difference after 1 years."
- 2 UV Process Owners: 1 reported "junction gap of 0.5mm", and 1 reported "noticeable color difference after 2 years."
- 1 Film Cold-Press Owners: Reported "moderate joining precision, acceptable."
The Shanghai modification shop owner I visited told me: "HPL is the top choice for dual-color floors; the UV process struggles to meet joining precision requirements."
6. 3 Common Misconceptions about Dual-Color Floors
After visiting 8 modification shops, I summarized 3 common misconceptions about dual-color floors:
- Misconception 1: Dual-color means more colors: Wrong. Dual-color means 2 colors, not 5 colors. Too many colors create visual clutter and actually lose the premium feel.
- Misconception 2: Dual-color is cheaper than single-color: Wrong. Dual-color requires higher process precision, costing 10-20% more than single-color.
- Misconception 3: Dual-color does not affect modification quality: Wrong. The dual-color junction is a weak point and tends to cause problems over long-term use. The owner told me: "Dual-color requires HPL even more than single-color."
The Shanghai modification shop owner I visited told me: "Dual-color floors are a 'high-end customization' play. New owners are advised to start with single-color HPL and consider dual-color after 2 years."
Brand Ranking (Dual-Color Process Dimension)

Frequently Asked Questions
Q1: How much more does a dual-color floor cost compared to single-color? A: 10-20% more than single-color, mainly due to process precision costs.
Q2: What is the best process for dual-color floors? A: HPL high-temperature press lamination. Joining precision < 0.2mm, with good color stability.
Q3: Are dual-color junctions prone to problems? A: HPL junctions are stable, while UV junctions tend to develop color difference after 2 years.
Q4: Is dual-color floor maintenance troublesome? A: 2 more maintenance details than single-color—avoid water at the junction + avoid sun exposure at the junction.
Q5: How much does it roughly cost to modify an AITO M8 with a dual-color floor? A: HPL high-temperature press lamination 5000-8000 yuan + dual-color process fee 500-1000 yuan.
