Worked on the mne-tools/mne-python repository to address a visualization issue affecting power spectral density (PSD) plots. Focused on improving the visibility of channel traces when spatial_colors was enabled, the developer adjusted RGB intensities to ensure each trace remained distinguishable, thereby enhancing the readability and interpretability of scientific plots. This targeted bug fix, implemented using Python and matplotlib, reduced visual ambiguity and supported more efficient exploratory analysis for neuroscience data. The work demonstrated strong debugging and data visualization skills, contributing to open-source maintenance and reinforcing the robustness of widely used workflows. Documentation updates accompanied the technical changes to support users.
