From: Ingo Molnar <mingo@kernel.org>
Boris reported that 'perf top' is unusable on his default 'black on white' terminal, which uses (eye friendly) light-grey as a background color.
The reason is that the TUI cursor for the current selection line uses HE_COLORSET_SELECTED, and that has a default background color of 'lightgrey' - which is a common terminal background choice and thus the colors conflict.
Use yellow as the background color instead: that should be an uncommon terminal background, yet it's still ergonomic on both black and white/grey terminals.
[ It would be a better solution to straight out detect color collisions and resolve them reasonably by converting them to RGB and calculating color space distances, but I was unable to find proper documentation for SLtt_get_color_object() to recover the current color scheme so I gave up ... Yellow works well enough. ]
