1. A method comprising, by a computing system:
- receiving ambient light measurements of ambient light of a scene from one or more light sensors of a vehicle, the ambient light measurements comprising one or more color wavelength ranges of the ambient light and an intensity of the one or more color wavelength ranges of the ambient light;
receiving an image captured by an optical sensor of the vehicle, the image comprising perceived color information associated with an object in the scene, wherein the perceived color information includes at least one color wavelength range associated with the image of the object;
comparing the one or more color wavelength ranges of the ambient light with the at least one color wavelength range associated with the image of the object;
based on the comparing, estimating a color associated with the object by using the intensity of the one or more color wavelength ranges of the ambient light and the at least one color wavelength range of the perceived color information associated with the image of the object;
determining the object based at least in part on the estimated color; and
providing instructions to perform a vehicle action in response to the determined object.

Abstract
In particular embodiments, a computing system may receive ambient light measurements of a scene. The ambient light measurements may be generated by one or more light sensors of a vehicle. The system may receive an image captured by an optical sensor of the vehicle. The image may include color information associated with an object in a scene. The system may process the image to estimate a color associated with the object based on the ambient light measurements and the color information in the image. The system may determine the object based on the estimated color and may provide instructions to activate a safety feature in response to the determined object.
