How to set the touch color of card component to white or invisible

In the advance properties there is an option to set the touch color of component.
I can set its color to green, yellow, etc but when I use white color, instead it shows grey on touch.

Is it a bug?

what is a solution to this?

You may try to make the touch color white and at the same time the background color of the button is white as well

I have a horizontal scroll arrangement with white background
Inside that i have card with white background, white stroke color and white touch color, still the output is grey when we touch the card.

Please suggest a solution to this.
