Individual
observer's data: GMZ
The
tables below provide individual observer data for the color selection
and the color adjustment part of the study, as tab delimited text.
For each part we provide two data files: one for the
illumination-constant condition, the other for the illumination-changed
conditons
(bluish and yellowish illuminant-changed conditions combined).
Color selection task
Selection data for
each condition: Illuminant-constant,
Illuminant-changed.
Data tables for both
conditions follow the same format:
Column 1: Condition code (NC for
illuminant-constant; CY and CB for yellowish and bluish
illuminant-change, respectively).
Column 2: Block number
Column 3: Trial type (denoted as a unique integer; refers to a
specific combination of target, competitor pair and illumination
condition)
Column 4: Target (1 for "Gray", 2 for "Rose"; 3 for "Teal" and 4 for "Green")
Column 5: First competitor in the
competitor pair on a given trial (Convention for illumination-constant
condition: 1= C-2,
2 = C-1; 3 =
T; 4 = C+1; 5 = C+2; For illumination-changed condition 1= T,
2 = C1;
3 = C2;
4 = C3; 5 = R; 6 = C5; See Figure 2).
Column 6: Second competitor in the
competitor pair on a given trial (same convention as in Column 5).
Column 7: Competitor chosen by the
subject on a given trial (1 = the first competitor in a pair, 2 = the
second competitor in a pair).
Column
8: Reaction time in seconds (from the trial onset until the subject
made a choice).
Column 9: Session order number
(tracked separately for illuminant-constant and illuminant-changed
conditons).
Figures
showing subject's choices and inferred matches (follows
the same conventions as Figure 3A):
Illuminant-constant, Illuminant-changed (yellowish),
Illuminant-changed (bluish).

predicted via MLDS procedure (pdf)
Different
illumination condition is plotted in each row: top -
illuminant-constant (NC); middle - illuminant-changed (CY); bottom -
illuminant-changed (CB).
Each
target is plotted in a different column (marked as T1 to T4). Each
subplot follows the same conventions as Figure S2 (supplement).

Figure follows
the same conventions as Figure A4 in the Appendix.
Color adjustment task
Adjustment data for each condition: Illuminant-constant,
Illuminant-changed.
Data
tables for both conditions follow the same format:
Column 1: Condition code (NC for illuminant-constant; CY and CB for
yellowish and bluish illuminant-change, respectively).
Column 2: Block number
Column 3: Trial type (denoted as a unique integer; refers to a
specific combination of target, competitor pair and illumination
condition)
Column 4: Target (1 for "Gray", 2 for "Rose"; 3 for "Teal" and 4 for "Green")
Column 5-7: Subjects'
adjustment-based match in
XYZ. NaN values denote cases when the subject chose option "match
impossible" or pressed pressing match impossible or match complete
button inadvertantly; these trials are not included in the analysis.
Column 8: Reaction time in seconds (from the trial onset until the subject
pressed match complete / match impossible button).
Column 9: Session order number
(tracked separately for illuminant-constant and illuminant-changed
conditons).
Figure
showing subject's adjustment-based and selection-based matches ploted
in CIELAB (pdf)
Different illumination condition is plotted in each row: top -
illuminant-constant (NC); middle - illuminant-changed (CY); bottom -
illuminant-changed (CB).
Subplots: L vs. a (left), L vs. b (center), a vs. b (right).
Competitor set for each target is plotted in open circles using a
matching color (gray, rose, teal, blue); filled circle denotes the
tristimulus match.
For each target and condition x symbol indicates mean adjustment-based
match (averaged across trials).
Inferred selection-based matches are plotted for reference (open
diamonds).
