Attempting to enter a layer number or parameter that's not supported according to this list, will result to a **B Integer out of range** error.

There's one more command of note and this is:

### LAYER CLEAR

which will reset all layer information, including banks, mode, the Layer 2 display enable, layer offsets (see *Chapter 17*) and ordering to defaults. This is also done by **NEW**.

### BORDER, PAPER, INK, BRIGHT and FLASH

Run this program:

```
  5 LAYER 0
 10 FOR m=0 TO 1: BRIGHT m
 20 FOR n=1 TO 10
 30 FOR c=0 TO 7
 40 PAPER c: PRINT "    ";:; 4 spaces
 50 NEXT c: NEXT n: NEXT m
 60 FOR m=0 TO 1: BRIGHT m: PAPER 7
 70 FOR c=0 TO 3
 80 INK c: PRINT c;"   ";:; 3 spaces
 90 NEXT c: PAPER 0
100 FOR c=4 TO 7
110 INK c: PRINT c;"   ";:;3 spaces
120 NEXT c: NEXT m
130 PAPER 7: INK 0: BRIGHT 0
```

This shows the fifteen colours (including white and black and the **BRIGHT** variants) that the ZX Spectrum Next can produce on the screen if switched to *Layer 0* (or standard resolution modes of *Layer 1*) without the *EnhancedULA* functions enabled. Here is a list of the basic eight for reference; they are also written over the appropriate number keys on your ZX Spectrum Next's keyboard:

0 black\
1 blue\
2 red\
3 purple –or magenta–\
4 green\
5 cyan –or pale blue–\
6 yellow\
7 white

If you're thinking to yourself that the total colours (taking account of brightness turned on) should be 16, you'd be technically right however there cannot be a BRIGHT black so the total amount of colours is indeed 15. As you've noticed, the program introduces three commands: **PAPER**, **INK** and **BRIGHT**. If you look back to the *Colour attribute display* section you will recognize the terms immediately. These commands are the primary way of applying colour to objects on screen in *NextBASIC*. There is a number of supporting colour commands as well which will examine further in the following sections.
LAYER 1,3	Select Layer 1, HiColour mode
LAYER 2	Select Layer 2 mode
LAYER 2,0	Select Layer 2 mode and disable its display
LAYER 2,1	Select Layer 2 mode and enable its display
