Yeah that's completely normal. I was born seeing auras and I still mostly see white auras keep working on it. Heres a tip inanimate objects auras are the esiest to see then plants then animals then humans.
I'm not very reliable for this but for me I've always been able to see white clear auras, but sometimes I see color, but it doesn't just suddenly happen. It kind of feels like you start to realize there are other colors and it usually depends on how open the person is. Seeing jut a clear aura for awhile is normal but if you try I'm sure you can acomplish more.
I've seen auras for as long as I can remember. When I was little I thought everyone could and I didn't realize it wasn't until my aunt explained that it was a gift. For awhile I wasn't able to see them and in recent years it's come back. I have been working to develop it again.
