I'm confused. This is for web, but you want Pantone colors?

it is for applications and web and we just give the colors for reference. so it matches.

Hi Project Owner!

Since there's quite a lot of icons to do, would you consider choosing a winner based
on received samples so that he/she can work on the rest knowing they will be paid?

Absolutely! Give us enough to get the idea of the style and that will work! I will update the brief to reflect!
