Changing the colour of your car is not illegal. Withholding the fact that your car is no longer black but red is illegal. Any color changes require you "by law" to inform Ministry of Transportation (or equivalent in your place of origin) as well as to inform the Insurance Company of this changes. Failure to do so may result in:
1 - Loss of insurance/No insurance coverage during an accident
2 - Fines or Probationary Term as per Federal law1
