Sample
Instantiating CanvasTexture defaults colorSpace to NoColorSpace ('') and drops any 10th colorSpace constructor argument, requiring explicit property assignment for sRGB rendering.

Commonly assumed
CanvasTexture defaults colorSpace to SRGBColorSpace or forwards a colorSpace constructor argument like Texture.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- CanvasTexture initializes colorSpace to NoColorSpace ('') and silently drops any 10th colorSpace constructor argument because its constructor accepts only 9 parameters.
- Base Texture constructor accepts colorSpace as its 10th argument and initializes colorSpace directly.
- Assigning colorSpace on CanvasTexture mutates the property directly without updating needsUpdate or incrementing texture.version.
- Cloning a CanvasTexture copies the colorSpace setting to the new instance, and toJSON serializes the colorSpace string.
