@SayanShankhari are the colors ok?

[SayanShankhari]

@bernborgess, there are a few contradictions with the contribution guidelines.

1. the dragon seems too complex to recognize in low resolution, can you re-use existing icon clone extension
2. the hexagon having M looks good, but it needs to fit the grid (check recently added feat(icon): nginx folder icon #3197
   )
3. usually there should be one color for the motive, unless the organization logo is too strict to change

Thanks for asking me, but please consult with core maintainers like @PKief and @lucas-labs. 😄

Sorry man, I just haven't had the time to look into this. Can you share a tool that would allow for such fixes? I've only taken the source svgs and I don't have experience manipulating them.

@bernborgess,

after checking the official icon for LLVM, taken just the head of the dragon and traced the paths in "inkscape" editor (renowned SVG editor), how do you feel about this? colors can be adjusted later on.

and here is the updated mlir icon, (again color can be adjusted)

and these files needs cleanup, do not commit with these

Hello @SayanShankhari , thanks for the reply. IMO the LLVM logo always features the dragon with spreaded wings, so that would be the most recognizable from afar. That's why I couldn't think of a lower detail version of said dragon that will fit your requirements. If there truly is no way to fit the wings, maybe the head will do.

Edit: I've found a video where only the head is used:

This is a good sign for your proposal!
