Colours abound! All 64 of them.

The Coco 3's standard colour palette

Introduction

The Color Computer 3, standard stock, has 64 colours to choose from, which can be placed into palette "slots". Below is a list of the colours in both Composite and RGB.

RGB vs Composite?

Australian Version addendum to the Color Computer 3 Manual.

I always wondered about the differences between RGB and Composite - mainly because I never had a Coco 3 growing up as a kid, but also because of this: Color Computer 3 Australian version addendum to the Australian Color Computer 3 manual. It states on the page:

PALETTE COMMANDS AND CODES

The Australian version ignores the commands PALETTE CMP and PALETTE RGB. The palette registers are present to the standard color attributed to RGB. Regardless of the kinds of display, disregard all code and color that are referred to CMP but use those of RGB.

As you can see below, the Australian version of the Coco 3 doesn't distinguish between RGB and CMP.

It's a bit of a shame really because I do like the composite colour palette. However, the composite colour palette looks to be very different between the two Coco 3 emulators, VCC and MAME.

Colour values

I thought that it might be nice to extract the colours from the RGB palette and composite palettes from the emulators. The RGB and HEX values for each colour are outlined in the following table.

The colour descriptions are derived from Coco 3 Secrets Revealed - Microcom Software/Spectrum Projects. Get it on the Color Computer Archive.
