Description

Replace the current gray Ethereum logomark PNGs and SVG with a version that remains legible across browser and theme environments, including dark mode and light mode browser tab backgrounds.

The current SVG has transparency behavior that differs from the PNG. On light backgrounds, the SVG appears gray; on darker backgrounds, it becomes nearly black, causing the inner geometry of the Ethereum mark to disappear. This is especially noticeable in browser favicons and is a bigger issue for the EIP site because its native styling is dark-mode oriented.

New Ethereum logomark

New logomark SVG

The new logomark SVG is grayscale, but less shadow-heavy than the current PNG. It provides stronger contrast and better shape definition in both light and dark contexts. The SVG is also used as the source for generating the fallback favicon PNG and the Apple touch icon.

Because this SVG may be useful outside favicon-specific contexts (it is used in the nav UI reworking in #9 inside the site title), and because the filename favicon is not required for icon tags, this change names the source asset logomark.svg instead.

Visibility comparison

The screenshots below compare three Chrome desktop browser tabs:

Light mode

All three logomarks are legible in light mode, but the middle example is the only one that reads as a clean gray mark. The others appear more shadow-heavy.

Dark mode

In dark mode, the issue is much more visible. The current PNG on the left appears overly shadowed, while the current SVG on the right becomes nearly black and loses its internal geometry. The new SVG in the middle remains the clearest and most recognizable option.

Use the grayscale Ethereum diamond as the reusable SVG logomark and primary SVG favicon.

Regenerate the PNG favicon and Apple touch icon from the same source, and keep the 16x16 PNG favicon as the fallback icon.
