Using this palette

Where stormy-sky leans green-gray to capture the specific sickly cast of severe-weather light, this palette stays in a cleaner blue-gray family, closer to how a storm system actually reads on radar or from a distance rather than the up-close, ominous green cast. #1C2B3A and #354B5E both carry white or #F0F4F7 text at strong contrast. #F0F4F7 works best used sparingly as a lightning/highlight accent against the darker blues rather than as a general background, which keeps the 'storm' read intact. Suits weather/outdoor tech, marine, or dramatic tech-brand dark themes.
