I'm adding Adrian on CC, as the original author of Frogr's icon (and also because my artistic abilities are a little bit more than questionable)

high contrast icon for frogr

this is the high contrast icon for frogr using inkscape.

Thanks sanchi for your submission.

I think it needs a bit more work to match the HighContrast style of thick black and white lines. Perhaps reading http://jimmac.musichall.cz/doc/high-contrast/html/index.xhtml might help.

Frogr icon, high-contrast version

Here is an icon based on the original Frogr icon, and applying the mentioned  guidelines for accessible icons.

Frogr icon, high-contrast inverse version

Same as the previous one, but with the white/black colors swapped so this version would better fit the inverse high contrast theme variant.

Thanks for the icons. Overall they look good to me, but I'm not an expert anyway in design guidelines, so I'd rather trust Jeremy's opinion to know when it's really a good moment to commit them to the repository.

Sanchi: Something is weird with your Inkscape grid settings, because the graphics keeps being off the grid.

Due to the lack of more comments, and considering that quite a long time has passed already :), I just took the high contrast icon provided by Adrian (the non inverse one) and pushed it to master.

Feel free to reopen if you do not agree with the decision or whether you feel the icon provided should be different, but for now let's at least have one.

Thanks!
