Compare Under The Sea and On Thin Ice to pick the right blue for your nails. Learn decision rules for cool, icy, and ocean blues in the Blue 42 Colors line.
Quick answer
Choose Under The Sea if you want a high-shine, ocean-blue gel strip with builder-gel strength for a bold, shimmering manicure. Choose On Thin Ice if you prefer long coffin-shaped press-on gel nails with a glittering icy blue ombre for a dramatic, cold-toned look.
Cool blue vs icy blue: what the difference means for your manicure
Cool blues lean toward ocean or aquatic tones, while icy blues have a frosty, glittering quality. Under The Sea falls into the cool-blue category with its ocean blue and aquatic shimmers, giving a vibrant, high-shine finish. On Thin Ice is an icy blue ombre with glitter, creating a colder, more dramatic effect. Your choice depends on whether you want a lively ocean vibe or a frosty, glamorous look.
Application method and wear time trade-offs
Under The Sea uses semi-cured gel nail strips that require curing under a Mini LED Lamp for 60 seconds, offering builder-gel strength and mega volume. This method suits those who want a salon-like gel finish at home and are comfortable with a curing step. On Thin Ice is a press-on gel nail that applies with a prep, size, and press process, which is faster and requires no lamp. However, press-ons may not last as long as cured gel strips, and removal is different.
When to choose each blue
Pick Under The Sea for events where you want a durable, high-shine manicure that can withstand daily wear, or if you enjoy the gel-strip application process. Choose On Thin Ice for a quick, dramatic look with a unique coffin shape and ombre glitter, ideal for a night out or when you want to change your nails frequently without curing.
