04:39 - color-contrast()

  • Part of CSS5! Maybe.
  • The color-contrast() functional notation takes a color value and compares it to a list of other color values, selecting the one with the highest contrast from the list.

06:01 - Accent color

07:34 - currentcolor

08:54 - Profiled color values - color()

11:00 - color-mix()

14:18 - Space-separated functional color notations

  • rgba(255 255 255 0) instead of rgba(255,255,255,0.5)

15:28 - RGB and HSL with Alpha

  • rgb() and hsl() can take alpha and percent values - rgb(0 0 0 / 50%) or rgb(0 0 0 / 0.5)

18:22 - Hex + Alpha values

  • How do you remember?!?!
  • Transparent

21:49 - lch(), lab(), hwb() notation

  • CIELAB color space aka Lab is a color space.
  • A color space is an organization of colors in coordination color profiling supported by various physical devices, it supports reproducible representations of color
  • Lab is intended as perceptually uniform
  • Perceptually uniform - a perceptual uniform color space ensures that the difference between two colors (as perceived by the human eye) is proportional to the Euclidian distance within the given color space.
