New design for open collective button

[juanis2112]

After our meeting we decided to change our open collective button to match the squared style icons we have in our page. @isabela-pf can you post your ideas on this issue?

Button styling is designed to match this button already on the docs:

I was originally working with #8c0000 as the new red (from the logo redesign), but it doesn't mesh well with the dark grey rgb(78, 78, 78) being used elsewhere on the website. Here's a screen shot of me testing it out:

Instead I found a different, brighter red that still meets accessibility standards for use with white text. This is #d50000. I also plan to work with this elsewhere on the website (like over in #24 as I try to set a color palette) and can try it with the logo for the next iteration since it works a lot better with the grey. Here's what #d50000 looks like on the grey in the footer:

Since GitHub doesn't support SVGs in comments, here's a link to the SVG.

@juanis2112, I think this is solved now, right?

Yes. Closing it now.
