The scene
Ceramics Studio · Pigment tableA blue sample prepared for the judges appears green. Three participants each had one bottle of pigment. Someone added pigment from their bottle to the sample cup.
The workshop keeps a results table made using those same quantities. You do not need any knowledge of painting: every possible mixture is listed on the sheet.
What we know for certain
One of these people added one dose from their own bottle to the blue sample, without help. They did not combine several pigments or remove liquid. The doses were identical to those in the table, and the colours can be distinguished unambiguously.
The three accounts
Jan Font
Apprentice«My bottle contained red pigment.»
Karla Roca
Ceramic artist«I was given the white bottle.»
Lino Prat
Designer«Mine was yellow.»

01The workshop’s table
With the doses used in this test, blue plus red makes violet; blue plus white makes light blue; blue plus yellow makes green.
02The result
The altered sample is green. A comparison analysis rules out both violet and light blue.
03The allocated bottles
The initial photograph confirms red for Jan, white for Karla and yellow for Lino. Each bottle remained with its owner.
04A single dose
The video shows exactly one dose being poured from one bottle. Afterwards the cup still holds the entire mixture.
05The initial sample
Before the visits, the cup contained only the blue dose stated in the table. There were no remains from other tests.
