Here is a point cloud containing $2^{15}$ particles for exploring the various color spaces (or, more accurately, exploring the projection of sRGB into these spaces). They have various purposes, but CIELab, OKLab, and CAM16-UCS are all designed to be perceptually uniform. This design is built to make it easy to see the differences and surprising variability between these three spaces, and contrast them against the famous sRGB space and the XYZ space (which is a convenient space for conversions and characterization of colors). NOTE: the scale of the spaces and their vertical positions are artbitrary and are chosen just for convenience of visualization. The design is more for comparing the general shape of the spaces.
Use the sliders to change the focus, which highlights an individual color and colors nearby, and feel free to interact with the color space itself, it can be rotated by clicking and dragging on it.
Additional sliders are given below for color blindness, where the dense region represents the subset of the space visible by someone with that type of color blindness, while the focused colors show the range of colors which someone of that type of color blindness may experience to be similar, causing the focus to take an elongated shape.
