Tryton Community Artwork README should mention license
IMHO the README needs to include guidance for when and how the "community artwork" can be used.
The community artwork README states the community artwork has been derived from the "official artwork"[1], which IIUC (and IANAL), which would require permission from the Tryton Foundation, as manager of the Tryton trademark[2], perhaps according to a license having terms of use.
IMHO a good example to reference is the Drupal Trademark and Logo Policy https://www.drupal.org/about/trademark
[1] https://downloads.tryton.org/images/ (referenced by @ced https://discuss.tryton.org/t/design-tryton-logo/6216/2)
[2] https://www.tryton.org/foundation (I presume the "official artwork" is either the trademark itself or incorporates the trademark)
