“…Despite widespread recognition of the weaknesses of the rainbow colour map, and of the wider issues associated with the use of red-green colour schemes, the results of this study suggest that both continue to be widely used in geoscience publications. The results presented here, in line with Stoelzle and Stein (2021), suggest there was a slight reduction in the use of data visualisations with colour issues in 2020; perhaps as (i) awareness of the issues associated with rainbow colour maps has grown, (ii) more journal reviewers and editors identify colour issues and request changes, and/or (iii) more tools and resources become available to support better decision-making with respect to colour schemes. Despite this, over half of geoscience papers published in 2020 still contain at least one visualisation that was ambiguous or non-CVD friendly, and any improvement from previous years appears to be uneven across different geoscience journals and so, by implication, across different geoscience disciplines.…”
