This is a port of an old color theme I used to use for xterm via .Xresources files. It's an off–white theme; background is LightYellow3, and bold/white text is inexplicably mapped to DarkOrange. The colors are all from X11 palette and give resonance with classic ANSI colors, but with some liberty to change hues to pick nice colors: eg dark magenta is DarkOrchid4, light magenta is HotPink, and bright yellow is GoldenRod2 or so. Most color combinations are legible without minimum contrast enabled, especially if you calibrate your colors well from the display system preferences screen.
