Description

It was pretty straightforward, because the logo is already provided in SVG. I only merged paths and removed colors. The hex color is the same used in the background of different elements inspected on the official website, that is the same as the mean of the gradient of the logo.

Note that the logo is public domain (source)

Okey, this time the problem was that the colinear segments I deleted were precisely the one causing the new problem (due to the change in the precision to 4). So to fix that I didn't remove the colinear segments, but adapted them to the new precision.
This time I checked against the real logo, I hope it worked hahaha.

Looks loads better! Thanks @MiguelMJ 🎉

I am however seeing a load of unnecessary points (see image below) that could potentially be removed to simplify the path and bring the file size down a bit. Did you want to take a look at this yourself, or would you like me to see what I can do with the points?

[MiguelMJ]

I can do it, thanks for the patience! 😅

[MiguelMJ]

I removed as many points as possible keeping the original shape. I think there's no more I can do, so if you want to take a look yourself, feel free 😄

Thank you very much!

Looks good to me! I tried simplifying further but there was too much difference to the original icon. Nice work @MiguelMJ 💪🏻
