Material

Colour mismatch

The color of the repaired element does not match the original paint of the adjacent parts - a difference that is especially visible at a certain angle of light or in daylight.

Cause

Color mixed according to an outdated or incorrect recipe - color formulas are updated by manufacturers, old versions produce different effects
Wrong selection of hardener or thinner - they affect the final shade and metallic effect
Incorrect working viscosity when sprayed - changes flake orientation and final color
The toners or base have not been mixed sufficiently before use - a heterogeneous mixture produces a different color
The color was not checked on the sample before application
Too many or too few layers of drop base - changes brightness and metallic effect
Poor gun setting - too much or too little pressure affects the final color tone
Mixing scale not calibrated or dirty - wrong toner proportions
Natural aging and fading of the original paint - the repaired element is new and the rest of the car is slightly faded

Prevention

Always check the color on a test sample before applying it to the element - in daylight and artificial light
Only use current recipes from the mixing system
Use hardeners and thinners recommended for a given product - they affect the final color
Check working viscosity before spraying
Mix and stir the toners at least twice a day
Calibrate your mixing scale regularly - once a year by a qualified service technician
Keep scales and mixing equipment clean
For older vehicles, take the fading effect into account - tint the color to match the faded original
Make a color sample and compare it with the original from different angles and in different light before painting the entire element

Repair

Mattify the top layer of the repaired element
Mix the color again taking into account the notes from the sample comparison
Check the color on the sample and, if necessary, correct the recipe or add additional colors
Reapply and compare with the original
If the difference is difficult to eliminate - shading onto the adjacent element is recommended for a smooth color transition
