In Roblox Rivals , dark blue usually corresponds to a rare tier, so it’s not common, but it also isn’t the top-tier hardest-to-get color. Community posts about Rivals-style rarity systems describe blue as the “rare” category, placed below higher tiers like legendary or mythical.

What that means

  • Blue = rare , so it should be less common than green/common items.
  • It is generally more obtainable than red or purple-tier items in games that use this kind of rarity ladder.
  • Exact drop rates for dark blue usually depend on the specific item or skin, and I couldn’t verify one universal percentage from the available sources.

Practical read

If you saw a dark blue item in Rivals, the safest interpretation is that it’s moderately uncommon rather than ultra-rare. In other words, it has some rarity value, but players typically see it far more often than the top cosmetic tiers.

Public discussion

A recent Reddit discussion about blue rarity in Marvel Rivals shows players treating blue as a lower rarity tier with simpler cosmetics, which matches the general “rare but not elite” idea.

TL;DR: dark blue in Rivals is usually rare , but not extremely rare.
