Where to find Citroen color code

How to Find Your Citroen's Color Code

Citroen paint color code is obtained by contacting Citroen to determine the color code. If no color code exists, the alternative is the PPG or Dupont (Axalta) paint formula number. In practice, Citroen supplies the code, or the PPG or Dupont (Axalta) formula number is used as the reference.

Your Paint Color Profile

Regate Blue Metallic

The Look

This color is a time capsule from 1979. It is a medium, technical blue that perfectly captures the "spaceship" aesthetic of the CX and the GSA. While it feels industrial and precise, it has a distinct French softness that keeps it from looking like a modern fleet color. Since your Citroen has been on the road for over four decades, the original finish has likely shifted toward a flatter, grayer tone. Your new application will likely look deeper and more vibrant than the aged panels surrounding it.

Technical Details

This is a metallic finish. It relies on thousands of tiny aluminum flakes to catch the light and create depth. The biggest risk with a metallic like this is mottling, where the flakes clump together and create dark, blotchy streaks. If the paint is applied too heavily in one spot, the finish loses its uniform shimmer and looks uneven. You want the flakes to lay flat and spread out, which requires patience and thin layers rather than one heavy coat.

Best Practices

On a 1979 model, you will usually find the paint code stenciled in a contrasting color on the firewall or bulkhead inside the engine bay. It might also be stamped onto a small plate near the suspension towers. Before you spray or dab Citroen Regate Blue Metallic (check for code AC-644), you need to shake the container for a full 60 seconds to wake up the metallic flakes. Test the color on the included card to see how the new pigment reacts to the light. Whether you are using a brush or a nozzle, keep the container moving to ensure the flakes stay suspended and land evenly on the surface.

Will absolutely order from this company again.

After ordering touch-up paint from Lexus I was still waiting for it a month later. If they'd told me upfront it would take that long I wouldn't have ordered in the first place. Paint Scratch was recommended by a friend who restores cars. Easy ordering, fair price and fast shipping. The color match is great especially considering my car is a 2012. Will absolutely order from this company again. Reason I chose this business: Lexus collision repair and a local collision repair. Will use paint less dent removal and touch up chipped paint myself. Reason I chose this product: Spouse sideswiped passenger side of car while backing out of garage. Mostly plastic transfer from his wheel well trim but pressure creased and cracked the paint causing a bare strip 1/8 wide x 4” long below door handle. Scratches on door handle and a few small chips on both doors.

Simply the best custom mixed paint in spray cans

Used Paint Scratch metallic custom mixed spray cans paint on a hood panel with excellent coverage and texture over the surface. Metallic paint can be very unforgiving out of a spray can, sputtering pigmentation dots on the panel being sprayed and thus ruining the paint job. No such issues with Paint Scratch custom mixed metallic paint spray cans. Paint sprayed strong and evenly till the last drop of paint in the can. Shipping time was faster than expected. Reason I chose this business: Having tried other brands of custom mixed metallic paint with terrible results, sputtering pigmentation tint dots from the spray nozzle in spite of vigorously shaking of can prior to application and loss of propellant rendering the lower fifth of the can's paint useless, Paint Scratch custom mixed metallic paint sprays out beautifully and strong all the way to the last gram of paint in the can. Simply the best custom mixed paint in spray cans for automotive restoration. Thank you Paint Scratch.

Frequently Asked Questions

How do I find my vehicle’s paint code?

Your paint code is usually found in the driver’s door jamb, trunk, or under the hood. See our Citroen Paint Code Guide for detailed instructions.

Will this paint match my car?

Because your Citroen is older or uncommon, the most accurate option is custom matching where you mail in a small painted part for a hand match. Our paint technicians usually do a great job matching Citroen color code 'AC-644' but a perfect match cannot be guaranteed.

Do I need primer and clearcoat?

While primer is recommended on bare metal or plastic, clearcoat is essential: it protects the basecoat and restores factory gloss.

How long does shipping take?

Orders are mixed fresh and ship within 3–5 business days. Delivery takes 2–14 days depending on location.

Which touch up product should I choose?

 It depends on the size of the damage:

  • Paint Pen (½ oz) – Best for very small chips and fine scratches.
  • Brush Bottle (2 oz) – Great for medium chips or scratches up to the size of a quarter.
  • Spray Can – Ideal for larger areas and panels.
  • Professional Sizes (Pint, Quart, Gallon) – Designed for full panel and vehicle resprays using spray equipment.

Not sure? If it’s just rock chips or small scratches, start with a Paint Pen.

Can I return my order?

Yes! If there’s a color match issue, we’ll replace the product or give you your money back. You also can return unopened, non-custom accessories for a full refund.

How long will the paint last in storage?

Paint pens and bottles last about a year if stored cool and dry. Spray cans can last several years if the nozzle is cleaned.
