> My initial instinct is that finding 12 colors that are visually distinguishable for all users is likely impossible. Without going to lightness extremes, I agree that this likely isn't possible, at least when trying to accommodate all three types of dichromacy and for small color patch sizes (like those typically used for line and scatter plots). For example, you could take the 10-color accessible palette from work I've published [1] and add black and bright yellow to get twelve colors, but the lightness extremes of adding these colors would result in significantly-different visual weights.…

For those interested, I've done some recent research on this topic [1], which tries to find cycles of colors that optimize both accessibility for color vision deficiencies, using simulations and minimum perceptual distances, and aesthetics, using crowd-sourced survey data.
