Differences in meaning: 'what about...?' vs. 'how about...?'

Hi,
Both of the phrases are used for some kind of suggestion or asking the other’s opinion on a certain situation, aren’t they? What I want to know is that there are ANY slight differnces between them except that each one uses a different interrogative.

I’m looking forward to your answers… thanks in advance.

Hi Sweetpumpkin,

There is a slight difference that I could illustrate. ‘How about?’ is often used with an action as in: How about going for a walk? This suggests: What do you think about going for a walk?

‘What about?’ is often used when someone is asking for a response to a choice as in: What about the blue one? That looks attractive. This suggests you are asking for an opinion for one thing from a number of different things.
