YouTube's primary color is pure red — literally #FF0000, nothing adjusted. Very few tech companies go that bold with a fully saturated primary hue, but it makes the play button one of the most recognized shapes on the internet.
The YouTube red is as pure as it gets: full-saturation red (#FF0000), the same value as the red channel in RGB maxing out. This directness is intentional — red means record, red means live, red means play. The dark background (#282828) used in the player and dark mode closely mirrors cinema projection environments. Together these choices reinforce YouTube's position as a serious video platform, not just a social feed.
