About colour family 680
Colour family from the 600 series: six solid colours and one metallic. The family sits in the dark, muted region with a blue hue.
The six solid colours. 680-1 through to 680-6. The range covers a wide lightness span, from L* 66 to L* 33. Position -1 and position -6 differ enough to work as a contrasting pair in a design.
The metallic. 680-M is matched to these six and intended to be applied alongside them, not as a replacement for any of the six. The metallic 680-M is clearly darker than the six solid colours. Never judge a metallic on a flat sample alone: viewing angle, film thickness and application method all help determine the result. Work with a sample in the final finish.
