Here is the chart of color for the US-Spec Celica from 1986-1989. If you see an error please post it here and I will correct the page and graphic ASAP. You can upload a photo of your car by clicking on the graphic, then clicking on the appropriate camera icon next to your color.
If you need me to update the chart please post your model year (or production date), color code and a description or photo of your car. For now this is for US-Spec cars only, I will add other countries in the future.
