Custom color does not match

[TheLastAurora]

Hey! I'm facing inconsistencies concerning the declaration of custom colors. I'm declaring them as the wiki says, but I'm getting weird behaviour, as the print above shows. I declared #15141a, but it shows that weird purple color, instead of a black.

[config]
# Global Matugen configuration

[config.custom_colors]
black = { color = "#15141a", blend = false }

[templates.vscode]
input_path = '~/.config/matugen/templates/vscode-colors.json'
output_path = '/tmp/vscode-colors.json'
post_hook = 'python3 /home/vitor/.config/matugen/scripts/update_vscode.py'
...

How I declared: "button.background" : "{{ colors.black.default.hex }}",
This persists in other templates as well.
