Custom Color Matching
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.
How Custom Color Matching Delivers Delta E <=1
The process begins with spectrophotometric measurement of your color standard in L*a*b* color space. ColoradoKote develops a custom Cerakote formula using controlled tint ratios and validates it through iterative refinement, typically two to four cycles. Once the formula achieves Delta E <=1, it is locked and documented for the full program duration, with every production lot validated against the master before coating begins.
Why Specialists Outperform Generalists on Color
Multi-service shops treat color matching as a secondary concern. Shared spray booths introduce cross-contamination risk, and operators splitting time across processes lack the repetition needed for precision color skills. ColoradoKote runs dedicated Cerakote equipment operated by Advanced Applicator-certified technicians who match colors every day. The result: a 90,000-part commercial aircraft program delivered with zero color rejections over three years.
AS9100 Color Traceability from Standard to Shipment
Every color match is documented under AS9100:2015 protocols. Records include spectrophotometer L*a*b* values, Delta E measurements against the master standard, coating batch numbers, cure profiles, and environmental conditions. Your Certificate of Conformance includes color measurement data alongside all standard quality documentation.
What you gain from precision color matching
Color inconsistency costs aerospace programs $50K-$200K annually in rework and delays. Precision matching eliminates those losses.
Spectrophotometric Measurement in L*a*b* Color Space
ColoradoKote measures color using D65 illuminant spectrophotometry, the standard aerospace programs require. L*a*b* color space quantifies lightness, red-green axis, and yellow-blue axis independently, enabling objective comparison against master standards. Environmental controls in the spray booth hold temperature within 5 F and humidity within 10% to ensure consistent color development through cure.
Formula Lock for Multi-Year Program Life
Once a custom color formula achieves Delta E <=1, it is locked for the full program duration. Sample retention for 10 years enables validation against the original standard on programs spanning decades. A 90,000-part commercial aircraft program was delivered with zero color rejections over three years using this protocol.
Eliminates $50K-$200K Annual Rework Costs
Color inconsistency costs aerospace programs $50,000 to $200,000 annually in rework and delays. Anodizing alternatives show 8-12% rejection rates with Delta E exceeding 5. ColoradoKote precision matching holds Delta E <=1 across production lots, eliminating color-driven rejections and keeping assembly schedules intact.

Your color standard is measured and archived
You provide a physical sample part, Pantone number, RAL value, Federal Standard 595 chip, or digital specification. ColoradoKote measures the target color with a spectrophotometer, capturing L*a*b* values under D65 standardized lighting. The master standard is photographed, documented, and stored in a climate-controlled archive for the full program duration. All records link to your purchase order, part number, and coating specification for complete traceability.
Every production batch is validated before coating begins
A test panel is coated and cured using production parameters before any customer parts enter the spray booth. The panel is measured against the master standard by spectrophotometer. If Delta E exceeds 1.0, the formula is micro-adjusted and re-tested. No production parts are coated until the batch achieves Delta E ≤1. This validation step is why the 90,000-part aircraft program maintained zero color rejections across three years of production.
Surface is cleaned and made ready for coating
Degreasing, cleaning, and light abrasion remove contaminants and create the ideal surface for adhesion. This step determines coating quality.
Parts are coated under controlled environmental conditions
Cerakote is applied in a climate-controlled spray booth held within 5 F of target temperature and 10% of target humidity. Calibrated HVLP equipment maintains consistent pressure and spray distance. Each coating batch is tracked by lot number, date, and applicator. Cure profiles are data-logged to ensure consistent color development, because cure temperature and duration directly affect final color appearance.
Ceramic coating is applied in controlled layers
We apply the coating using precision equipment, monitoring thickness and coverage. Each layer cures before the next is applied, building a durable finish.
First-part inspection confirms color conformance
The first coated part from every production lot is measured by spectrophotometer against the master standard. Delta E is recorded in the AS9100 quality system. Parts are also inspected under a D65 lighting booth that simulates natural daylight. Any part with Delta E exceeding 1.5 is flagged for engineering review. Your Certificate of Conformance includes L*a*b* color data alongside thickness, adhesion, and visual inspection results.
Coating hardens and bonds to the substrate
The coating cures under controlled temperature and humidity. We don't rush this phase. Full cure strength takes time, and we give it that time.
Color formulas and samples are retained for your program
One coated part from each production lot is archived in climate-controlled storage with a 10-year retention period. The custom color formula and cure profile are frozen for the full program duration. ColoradoKote monitors color stability across multi-year programs, and NIC Industries maintains Cerakote formulation consistency at the manufacturing level. When you order replacement parts in Year 5, they match Year 1 production within Delta E ≤1.
Every part is measured and tested before shipment
We measure coating thickness, check for defects, and verify specifications. Documentation is prepared for your records. Only parts that pass leave our facility.
Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Standalone ultrasonic cleaning turnaround is typically 3-5 business days from receipt of parts. Cycle time per batch is 10-30 minutes depending on contamination severity, but turnaround includes intake, pre-assessment, cleaning, verification, and documentation. For parts proceeding to coating, cleaning is integrated into the coating schedule and does not add separate lead time. Contact us at 970.541.7331 for current scheduling availability.
We use a multi-method verification approach. Water-break testing confirms DI water sheets uniformly across surfaces with zero beading, verifying the absence of oils and films. White-glove inspection checks for particulate transfer. For critical aerospace applications, dyne pen testing measures surface energy against your specified threshold. Rinse water conductivity is verified below 10 microsiemens per centimeter. Parts that fail any verification step are re-cleaned before release.
Yes. While ultrasonic cleaning is frequently performed as surface preparation before coating application, we also provide it as a standalone precision cleaning service. Standalone cleaning orders receive the same AS9100 process controls, documentation, and verification as cleaning performed before coating. Parts are returned clean with a Certificate of Conformance documenting all cleaning parameters and verification results.
Ultrasonic cavitation removes machining fluids, cutting oils, coolant residue, fingerprint oils, mold release agents, flux residue, carbon deposits, embedded particulates, and additive manufacturing support material. The cavitation action reaches contaminants in blind holes, internal passages, threads, and lattice structures that manual cleaning and spray methods cannot access. Solution chemistry is selected based on the specific contamination type and substrate material.
No. Ultrasonic cavitation is a non-contact cleaning method that does not mechanically abrade or distort parts. Cleaning solution chemistry is matched to the substrate material to prevent chemical attack. Alkaline solutions are used for aluminum, neutral formulations prevent hydrogen embrittlement on titanium, and polymer-safe solutions protect additive manufacturing parts. We have cleaned parts with wall thicknesses under 0.5mm without damage or dimensional change.
