* Fix #92539: Hard to read the breadcrumbs. * Fix View Item active, hover, and text color (e.g. count numbers in the Spreadsheet were almost unreadable). * Fix mismatching node type colors with the default theme. Blender Light is meant to be simply a brighter version of the default, so screenshots and tutorials can be followed with both themes. * Use the same outline color for widgets, so they match when aligned in a row. * Make panels standout (not fully transparent), like in the default theme.
