The authors studied how different color palette tools affect the way designers create colors for data, especially when they need to consider both how things look and how easy it is for people to see the colors. They had 40 designers use four different tools to complete design tasks focused on accessibility and aesthetics. They found that the choice of tool made a bigger difference when designers had to meet accessibility needs, and some tools naturally encouraged designers to think more about accessibility even if it wasn’t required. This suggests that how a tool is designed not only affects the final colors but also what designers pay attention to during their work.

Abstract
Designing a color palette for data requires designers to balance multiple constraints, including accessibility and aesthetics. Color palette tools support this process through features including direct manipulation, automated palette generation and evaluation, previews, and so on. Despite their prominence, relatively little is known about how these different mechanisms shape design across contexts. We conducted an exploratory think-aloud crowd work study with 40 self-identified designers. Each participant used one of four palette tools selected to span different interaction modalities to complete a series of accessibility- and aesthetics-oriented design tasks. We observed two preliminary patterns. First, tool differences were more pronounced in accessibility-constrained tasks. Second, even when accessibility was not explicitly required, some tools produced more accessibility-friendly palettes and prompted more accessibility-oriented thinking. In this tool genre, then, system design shapes outcomes both via built-in functionality, as well as by directing designers' attention toward particular constraints and design considerations.
