This study aims to identify the correlative color temperature (CCT) of the most adequate artificial lighting throughout the day, considering the dynamics of daylight, for tasks that require attention. Three CCT conditions are examined (3000K, 4000K and 6500K) and the Toulouse-Pierón Attention Test was used to measure focused attention in the three shifts, but in the morning and afternoon was also made with and whitout daylight. After this, a self-reported about light quality was answer. The results were organized and assessed in electronic spreadsheet and the partial analyzes, indicate that the best performance is given to 6500K, regardless of the presence or absence of daylight, except for the afternoon shift with sun whose best situation is 3000K.
