Nav Icons Font and Colours

[jstet]

          Thanks! I like the elements and think that they could be useful on other pages. 

Looking at them on my big ass monitor screen, i have two concerns:

• font: i don't think the font is well readable from an accessibility perspective when it is so small. i know we have been using it on canva for a bit but i feel for this, it is not so well suited (the letters "mush together" even for me).
• colors: maybe we could think about different colors for the backgrounds of the icons? I think right now it implies too much of a "sequence". in [correltools](https://github.com/CorrelAid/correltools) , there the opportunity to create qualitative palettes:

scales::show_col(correltools::correlaid_pal()(5))

or is this too many different colors? IDK.

@friep i have increased the font spacing, size etc. Does it work better now?

I intentionally used a sequence of colours so it fits to the gradient of the hero etc.
