'''BCALL Address:''' 5626h

Look up the RGB value for one of the 15 standard colors in the graphing color palette.

=== Inputs ===
* A = color index (1 to 15)

=== Outputs ===
* DE = color value (RGB-565)

=== Destroys ===
* F

== Comments ==
The palette used by this routine is as follows:
{| style="border-spacing: 0.5em 0.25em"
! Index !! Value !! R !! G !! B !! Name
|-
| 1 || 001F || 0 || 0 || 31 || Blue
|-
| 2 || F800 || 31 || 0 || 0 || Red
|-
| 3 || 0000 || 0 || 0 || 0 || Black
|-
| 4 || F81F || 31 || 0 || 31 || Magenta
|-
| 5 || 04E0 || 0 || 39 || 0 || Green
|-
| 6 || FC64 || 31 || 35 || 4 || Orange
|-
| 7 || B100 || 22 || 8 || 0 || Brown
|-
| 8 || 0010 || 0 || 0 || 16 || Navy
|-
| 9 || 049F || 0 || 36 || 31 || Light Blue
|-
| 10 || FFE0 || 31 || 63 || 0 || Yellow
|-
| 11 || FFFF || 31 || 63 || 31 || White
|-
| 12 || E71C || 28 || 56 || 28 || Light Gray
|-
| 13 || C618 || 24 || 48 || 24 || Medium Gray
|-
| 14 || 8C51 || 17 || 34 || 17 || Gray
|-
| 15 || 52AA || 10 || 21 || 10 || Dark Gray
|}

A = 0 (which, in the graph buffer, represents a "transparent" pixel) also returns white. Values of A greater than 15 will return garbage.
