It's federal law under FMVSS 108 in the US and CMVSS 108 in Canada. Both of them reference SAE J578, which requires side marker lights to be amber.
For once it's not just government overreach. There's actually a reason for it, and that reason is that white light and blue light impair night vision, whereas amber and red do not. If you look at a red light and then into a dark area, your ability to make out detail is much better than if you look at a white light. This is why pilots use red lights in their cockpits, so that if they look outside, their night vision is not impaired.
Somewhere along the way this made it into our motor vehicle codes so that drivers are not staring into white lights on cars in front of them, losing their night vision and becoming unable to see threats in dark areas off to the side. Ever notice how annoying and fatiguing it is to ride along behind someone whose rear brake lens is broken? This is why. Even a douchey white side bulb can be enough to impair a driver's night vision, because the driver's eye adjusts to it.
So I'm not all that concerned that it's against the law. I'm against it because it's douchey and annoying to other drivers.

As far as I know, turn signals are legal being white. Besides, these are marker lights. Not turn signals.

Rear- and side-facing turn signals have to be amber or red. A white side-facing turn signal is douchey.
I should mention that I actually like the clear side markers and eventually plan to put them on my car. But I'll install them with amber bulbs so that I'm not annoying other drivers.
