Remapping a mark whose color is part of its identity - a red-outline
wordmark with white fill, a colored badge - fixes legibility but changes
the logo's character, which reads worse on hero surfaces than the
partial invisibility it cures.
The light tone class now splits on measured colored-pixel fraction:
light-dominant marks with incidental color (<=15% saturated pixels,
lightAccented) always remap, while lightMixed marks remap only when the
new ToneMappedLogoImage.remapMixed policy allows it. Heroes pass false
on the network, offline, and TV spotlight logo paths; the Live TV
guide's channel cells keep remapping mixed marks. The policy joins the
image-cache key. The threshold comes from a real clear-logo set:
remap-friendly marks measured at <=0.11 colored, identity-colored marks
at >=0.28.
White-on-transparent broadcast logos (CBS, FOX, the NBC wordmark) vanish
on the light theme's white guide cards, making channels hard to identify.
Channel logo decodes now classify the frame's tone once per image-cache
entry and bake light-neutral pixels toward the theme foreground:
monochrome white marks recolor fully, mixed marks (colored peacock plus
white wordmark) keep their colored pixels, and self-backed or dark
artwork decodes unchanged. Applied in the guide channel column, guide
search, and favorite reordering whenever the backdrop is light,
including the dark theme's inverted focus card; dark backdrops keep the
original artwork.
