Adjust wallpaper accent calculation to increase contrast and vibrancy
Right now, the calculation prefers the image's dominant color, which is
likely to be a color from the background. As a result, it often returns
a color that is very dark or muted, especially with wallpapers based on
night landscaped or space. The darkness is especially problematic when
using a dark color scheme, where it causes contrast issues. It also has
the effect of making the selection highlight on the desktop hard to see
since by definition, its color will be very similar to the most common
color in the wallpaper.
This commit adjusts the wallpaper accent color calculation as follows:
1. Consider a narrower range of lightness values acceptable; now the
lightness has to be at least 0.4, and it can't be darker than 0.75.
This fixes most of the contrast issues.
2. Try the wallpaper's highlight color before the dominant color. This
tends to pick the color in the wallpaper that is most likely to draw
the user's attention, even if it's not the most common color. It also
tends to be a richer and brighter color compared to the dominant
color, so the extracted accent color is more likly to be bright and
pretty rather than dark and muted.
3. If the highlight color or dominant color isn't within the specified
lightness range, lighten or darken it and try again. This makes the
algorithm work harder to try to give you a color based on the
highlight color or the dominant color and avoid falling back to the
average color, which is highly likely to return a drab, muted color.
