I’ve noticed this in pictures from accross asia, including india, singapore, and myannmar. This doesn’t exist in European or American road signage systems.
I feel like a quick web search could answer that, but I’m not going to do it either.
In US curbs where you can’t park are painted bright yellow/orange, so I assume it’s something like that.
Going off this India traffic police site same as a white curb. High visibility marking the edge of the road.
You picked a picture of outside a prison…
It could just mean “no parking” and not be on every curb
Generally, the color of the curb indicates where or not you can park a car there and for how much time. It may also indicate if it is reserved for a dedicated veihcile type.

I suspect this is a remnant of the British era. Don’t quote me on that. In Belgium we have yellow panted stripes to indicate you’re not allowed to park. Similar.
I always though it was at the UN agreement for road signaling.
A lot of countries that that same standard.
Not 100% sure in the case of Singapore, but the double yellow lines indicate no stopping.
For places where we are allowed to park on the sides of the roads, there are either lot spaces already allocated and drawn out, or there will be no lines painted on the road.
Double yellow lines in the picture here indicates no stopping at all times, so it would be a little pointless to have the curb indicate no parking again.
The curb might just be for visibility, can’t confirm.
Zebra crossing
