GM Color Code Picker: Quickly Find Any GM Paint Hex & RGB

GM Color Code Picker Guide: Identifying GM Paint Codes by Year and Model

Matching the exact exterior or interior paint on a GM vehicle requires knowing the correct GM color code and how it maps to modern digital color values (HEX, RGB). This guide explains where to find GM paint codes, how codes changed over the years, and how to use a GM color code picker to get accurate color values for restoration, touch-ups, or digital design.

How GM paint codes work

• Format: GM paint codes are typically 2–4 characters (letters and/or numbers). Older codes (1950s–1970s) are often two digits or a letter+digit; later codes can be three characters (e.g., 76U) or four (e.g., G1B).
• Components: Codes may represent base color, shade, metallic/flakes, or manufacturer options. Some vehicles use separate codes for base and stripes/accents.
• Location: Codes are printed on the vehicle data plate/sticker, often found in the glove box, door jamb, trunk, or under the hood.

Finding the color code by year and model

1. Locate the data plate/sticker:
   • 1960s–1980s: metal tag or paper sticker in the glove box or driver door jamb.
   • 1990s–present: Service parts identification sticker (SPID) in glove box, trunk, or under seats.
2. Read paint code fields:
   • Look for “Paint,” “PAINT CODE,” “BC/CC” (basecoat/clearcoat), “EXT PNT,” or a 2–4 character string that matches typical GM formats.
3. Cross-check with build sheets and VIN-based decoders:
   • Some models used internal option codes rather than simple color codes; VIN decoders or factory build sheets can confirm the paint option for a specific production run.

Common year-by-year variations

• Pre-1968: Simple numeric or alphanumeric codes; some colors varied by trim level.
• 1968–1979: Two- and three-character codes; a larger palette with special-order colors.
• 1980s–1990s: Transition to standardized codes and introduction of metallics.
• 2000s–present: BC/CC system, clearer separation of basecoat and clearcoat codes; many special finishes (pearlescent, chromaflair) use separate identifiers.

Using a GM Color Code Picker tool

• Enter the paint code: Input the exact characters from the data plate. The picker should include historical databases for older codes.
• Select year and model if required: Some color codes were reused across years with different hues; specifying year/model increases accuracy.
• Convert to digital values: The picker gives HEX and RGB for digital work, and often PPG/PPG equivalents for bodyshops.
• Check finish type: Confirm whether the value represents basecoat only or base+clearcoat/metallic effect; pickers may show versions for matte, metallic, and pearl.

Tips for accurate matching

• Age and fading: Original paint fades; match using a fresh, unrestored panel or factory chips when possible.
• Wet-sanding and blending: For spot repairs, blend new paint into surrounding panels to hide slight hue differences.
• Use professional mixing codes: Body shops use manufacturer or supplier mixing formulas (PPG, Glasurit). A color picker may provide these or conversion references.
• Test panels: Always spray a test panel in the same conditions (temperature, humidity) and apply clearcoat before final approval.

Troubleshooting mismatches

• Code not found: Try alternate label locations, check VIN/build sheets, or consult historical GM color catalogs.
• Close but not exact: Verify whether the vehicle received a repaint; factory option vs. dealer respray can differ.
• Special finishes: Pearlescent and color-shift paints often require layered mixing; rely on supplier formulas rather than HEX alone.

Tools and resources

• Use a GM color code picker that includes a historical database and conversion to HEX/RGB.
• Factory color chips, OEM paint suppliers, and bodyshop databases (PPG, BASF) are best for physical repairs.

Quick checklist before ordering paint

1. Locate vehicle paint code on plate/sticker.
2. Confirm year and model to resolve reused codes.
3. Use a reliable GM color code picker to get HEX/RGB and supplier formulas.
4. Order a test sample or small can for verification.
5. Apply test panel and adjust mix as needed before full application.

For restoration or precise digital work, pairing the code picker output with supplier mixing formulas and test panels gives the highest chance of an accurate match.
