When I choose a variable font in Paint.NET, it would have the first style of the font, for example, the first style for "SF Pro Display" is Ultralight, so it would have the Ultralight style, and when I bold the text, it would choose the Bold style.
This design is my attempt on a website design based of on Neubrutalism, which is a design trend with muted and clashing colors, no gradients, and it's typography.
For a way better realistic effect (90s), you use Motion Blur and Emboss.
For a 2000's VHS effect, you use centred Motion blur and then do non-centered motion blur.
