We just had to go into IT's RH-SSO deployment and update our custom themes to match the new brand but I noticed that our internal-facing administration pages are still displaying the old brand since that's the stock RH-SSO theme.

Update images in the rh-sso theme to comply with the new brand standards: https://www.redhat.com/en/about/brand/standards

From what I could tell the affected files in themes/src/main/resources-product/theme/rh-sso would be:
welcome/resources/logo.png
welcome/resources/favicon.ico
common/resources/img/favicon.ico
common/resources/img/brand.svg (due to the font change)
common/resources/lib/rcue/fonts (new font download?)
common/resources/lib/rcue/img/apple-touch-icon-precomposed-*.png
common/resources/lib/rcue/img/favicon.ico
common/resources/lib/rcue/img/logo.svg
