Color theory is complex when it comes to recording and playing back colors accurately due to the involvement of various systems such as software, video decoders, video cards, and monitors. To standardize this process, color standards were developed. However, advancements in technology like digital television, compression, and display changes have made the process more complicated. A solution is creating a new "colorspace" for new HD content while mapping older colorspaces to the new one. This makes video production more complex as every step needs to consider which colorspace is being used. Two common colorspaces today are BT.601 (SMPTE 170M) and BT.709, with BT.2020 becoming popular due to HDR and UHD content. The process of encoding video files can sometimes go wrong, leading to incorrect color rendering. This is often due to missing or incorrect colorspace metadata in the file. It's crucial to always set the colorspace metadata on videos, as it helps maintain accurate color representation across different devices and platforms.
