Cobalt

Retired

1987-2021 · Color No. 105

Introducing Cobalt, made by The Fiesta Tableware Company from 1987 to 2021. It's a rich and vibrant shade of blue, reminiscent of the deep blue hues of the ocean. Cobalt adds a bold and striking touch to any tablescape. Mix and match Cobalt with colors like White and Turquoise for a refreshing and nautical-themed table setting, or pair it with Poppy and Sunflower for a dynamic and energetic combination.

Notes on Cobalt

Post 86 Cobalt arrived in 1987 with Rose and Yellow, reviving the name from the original 1936 palette, and it ran thirty-four years before retiring in 2021 - one of the longest runs in the line. It's a deep, near-navy blue that anchors a table the way nothing else in the modern palette does. Worth knowing: this and the vintage Cobalt are close enough that a photo won't separate them, so if you're buying online, the color number is what settles it. Post 86 pieces carry No. 105; vintage ones predate numbering entirely. Twilight, introduced in 2021, is the closest modern replacement.

Using Cobalt on a table

Cobalt is soft enough to sit beside almost anything. It works as a bridge between two stronger colors that would otherwise argue. At L* 17 it is a genuinely dark plate, so pale food stands out on it and dark food disappears. It separates strongly from a white cloth (14.5:1) and less so from dark wood.

Where Cobalt sits in the line

Cobalt took over from Turquoise, 1937-1969 as Fiesta's blue, and is noticeably darker than it - a complete change of direction rather than a reformulation (ΔE 50.5). It has been in production 34 years against a median of 7 for its era - one of the colors the company kept. In 1987 it arrived alongside Rose, 1987-2005 and Yellow, 1987-2002.
