The new profile themes allow users to choose arbitrary colors for text, buttons, icons, and backgrounds. Some combinations can make functional UI difficult or impossible to read, for example, white text on a bright yellow button. This is primarily a readability and visual-comfort issue. Poor contrast can affect users with low vision, color-vision deficiencies, migraines, light sensitivity, or other visual-processing difficulties. It can also be especially uncomfortable in VR headsets. Please add an accessibility option that lets viewers override custom profile themes with VRChat's default colors. Ideally, this would include a global toggle to show/hide custom profile themes, automatic use of default colors when a high-contrast accessibility mode is enabled, or contrast validation in the theme editor to prevent unreadable combinations. Profile customization is a nice form of self-expression, but the viewer's accessibility and readability preferences should take priority over another user's theme.
