 | [`strip.now`](https://github.com/wled/WLED/blob/main/wled00/FX.h)                  | 32-bit | Current timestamp in milliseconds.  (Equivalent to `millis()`, but use `strip.now()` instead.) |
 | [`SEGLEN / SEG_W / SEG_H`](https://github.com/wled/WLED/blob/main/wled00/FX_fcn.cpp)                        | 16-bit | These variables are macros that help define the length and width of your LED strip/matrix segment. |
-| [`SEGPALETTE`]((https://github.com/danewhero/WLED/blob/user_fx/wled00/FX.h)                            | ---    | Macro that gets the currently selected palette for the currently processing segment. |

 | [`SEGCOLOR(x)`](https://github.com/wled/WLED/blob/main/wled00/FX.h)                                   | 32-bit | Macro that gets user-selected colors from UI, where x is an integer 1, 2, or 3 for primary, secondary, and tertiary colors, respectively. |
 | [`SEGMENT.setPixelColor`](https://github.com/danewhero/WLED/blob/user_fx/wled00/FX_fcn.cpp) / [`setPixelColorXY`](https://github.com/danewhero/WLED/blob/user_fx/wled00/FX_2Dfcn.cpp)       | ---    | Fuction that paints a single pixel to your specified color.  `setPixelColor` assumes 1D array and requires one positional argument, while  `setPixelColorXY` takes two positional arguments (x and y), and then the RBG color value. |
