Notes. Every field is two-way: edit it and everything else follows. The byte-swapped box is what most ESP32 SPI panels expect — ST7789 / TFT_eSPI / Adafruit_GFX push the high byte first, so 0xA01F goes on the wire as 0x1FA0. RGB565 is lossy; the small preview tag shows the actual color the panel renders. Pantone matching is a nearest-neighbour against a built-in sRGB approximation set (CIELAB) for both PMS Coated and TCX Fashion-Home-Interiors. Type a TCX code (e.g. 11-4201), a TCX name (Cloud Dancer), or a PMS code (286 C) into the Pantone box and it snaps. These are approximations, not spec-accurate spot colors. ΔE is CIE76 distance.
