I want to achieve classroom greenboard effect(just the green colour with chalky powder effect) using css like in the image shown below

![enter image description here](https://i.stack.imgur.com/EpRuw.jpg)

I have found the font which is close to the writing but for the greenboard I tried picking the colour and applied as a background to the div,but it all looks plain and uniform,which is unrealistic.

Can I achieve that whitish-green effect using CSS?I don't want to use image for that.

(I believe its possible because once I saw a person made a full Coke Can using pure CSS)
