SGTM. Do you need assets for the download shelf and downloads page? Please assign to myself or max for traige.

A plus would be to attach the existing assets being used in both areas. 

Thanks, bettes@! Assign it to you for triaging. 
The warning icon on download shelf is a legacy icon which resides at https://cs.chromium.org/chromium/src/chrome/app/theme/default_200_percent/legacy/safebrowsing_warning.png

And the warning icon on chrome://downloads page is a svg icon https://cs.chromium.org/chromium/src/ui/webui/resources/cr_elements/icons.html?rcl=0&l=40

Can we just re-use the triangle asset from the omnibox for this? Or does it have to be re-sized or something?

The red triangle should replace any "circle with dash" and yellow triangles. 

Attached is a 48x48 png asset and a svg for the danger triangle. Color svg #DD4330 if used.
