## 4 Discussion  
The information derived from the current research, which aggregates findings from three experimental conditions described above in relation to coloured light scenarios, yields remarkable implications that facilitate considerable generalisations. In approaching this section systematically, we begin with net attention, considered as a crucial dimension of the variable 'cognitive processes'. In this regard, the existing literature reveals multiple avenues for discourse. [PERSON] et al. [22], in their analysis of CCT, underline the fundamental role of illumination in attention. At the same time, [PERSON] et al. [24] state that exposure to cold light improves concentration, while [PERSON] et al. [23] conclude that high CCT values positively influence attention. Focusing specifically on coloured lighting, [PERSON] et al. [12] propose that a dynamic, coloured lighting system can improve the attention of primary school pupils, with the violet phase producing the most favourable results. In a subsequent investigation by the same authors [59], violet light re-emerges as the optimal condition for improving attention. The current study corroborates these findings. \begin{table}

Thus, all scenarios with coloured light in the experimental group show superior results compared to the natural scenario, although the control group shows generally high values (indicating a clearly superior baseline for the control group compared to the experimental group).
