So while clicking on any of the clickable component in Compose, i see that there is a grey color bar comes up for a sec, can we customise that effect, may be to a different color

Yeah, you want to pass an indication parameter to Clickable - Material provides rememberRipple() for this

If you are using a MaterialTheme (doesn't look like you are using Material components) then it will provide a default value for LocalIndication, which is where this grey bar is coming from (the default debug value) - so you could override this with a ripple or your own custom indication

If possible can you point me to a sample, how to implement a Indication of our own

Here's how the default debug indication (the one in the video) is built:

And here's how a Ripple is built (more complex):
