Medium vs Dark Spray Tan: How to Choose the Right Shade

Choosing between a medium and a dark spray tan is one of the most common decisions clients face — and one of the most important. Pick the right shade and you’ll look naturally bronzed and sun-kissed. Pick the wrong one and you could end up with a color that doesn’t match your complexion or feels too dramatic for your comfort level.

The good news is that this isn’t a guessing game. The difference between medium and dark spray tans comes down to DHA concentration, and when matched to your skin type and undertones, both options can look absolutely natural.

Here’s everything you need to know to choose the right shade.

What Makes a Spray Tan “Medium” vs “Dark”

The depth of a spray tan is determined primarily by the percentage of DHA (dihydroxyacetone) in the solution. DHA is the active ingredient that reacts with the amino acids in your dead skin cells to produce color. The higher the DHA concentration, the deeper the color development.

In professional-grade solutions, the breakdown typically looks like this:

• Light: 6% DHA — subtle, sun-kissed glow
• Medium: 9% DHA — noticeable warmth, the most popular shade
• Dark: 12% DHA — rich bronze, deeper color
• Dark Depth: 14% DHA — deep, dramatic bronze

When most people ask about “medium vs dark,” they’re comparing the 9% and 12% DHA options. That 3% difference might sound small, but it produces a meaningfully different result on the skin.

What a Medium Spray Tan Looks Like

A medium spray tan (9% DHA) is the most versatile and universally flattering option. It’s the shade most first-time clients choose, and for good reason — it adds visible warmth and color without looking like you’ve done anything dramatic.

On fair to light skin (Fitzpatrick types I–II), a medium tan creates a noticeable golden glow. You’ll look like you just spent a long weekend at the beach. On medium skin tones (type III), it deepens your natural color into a rich, even bronze. On olive to brown skin (types IV–V), it adds depth and radiance without changing the fundamental character of your complexion.

Medium is the safe choice for everyday wear, work environments, events where you want to look polished but not overtly tanned, and any time you want results that look believable on your natural skin tone.

What a Dark Spray Tan Looks Like

A dark spray tan (12% DHA) is a step up in intensity. It produces a deeper bronze that’s more noticeable, more dramatic, and best suited for clients whose skin can support the extra color without looking unnatural.

On lighter skin tones (types I–II), dark can work, but it’s a bigger jump. If your natural complexion is very fair, a 12% solution may look more like a tan you “got” rather than one you naturally have. That might be exactly what you want — or it might feel like too much. If you’re fair-skinned and considering dark, talk to your spray tan artist about doing a trial session first.

On medium to brown skin tones (types III–V), dark looks stunning. It enhances the skin’s natural warmth and produces a rich, deep bronze that looks completely believable. For clients with deeper complexions, dark (or even dark depth at 14%) adds an even, luminous glow that catches the light beautifully.

How Undertones Affect the Outcome

The DHA percentage isn’t the only thing that determines how your tan looks. The undertone of the solution plays a major role in whether the final color appears warm and natural or slightly off.

Professional spray tan solutions typically come in two undertone families:

Olive (green) undertones — Best for cool and neutral skin tones. The olive counteracts any pink or red in the skin, producing a golden-brown result. If your veins appear blue or purple on your wrist, you tend to look better in silver jewelry, or your skin leans pink, olive-undertone solutions are likely your best match.

Violet undertones — Best for warm and neutral skin tones. The violet deepens the naturally warm tones in the skin, creating a rich chocolate-brown finish. If your veins appear green, gold jewelry suits you, and your skin leans yellow or peachy, violet-undertone solutions will complement you well.

Getting the undertone right matters just as much as choosing the DHA percentage. A medium tan in the right undertone can look more natural than a perfectly matched DHA percentage in the wrong undertone.

Medium vs Dark: A Side-by-Side Comparison

Here’s a quick breakdown to help you decide:

When to Choose Medium

Go with medium if you want a natural “I just came back from vacation” look, if it’s your first spray tan, if you have a professional setting that calls for subtlety, or if you’re naturally fair and want results that look believable. Medium is the all-around crowd-pleaser — versatile, forgiving, and flattering on nearly every skin type.

When to Choose Dark

Go with dark if you want more visible color depth, if you have a medium or darker natural complexion, if you’re prepping for a special event (vacation, wedding, photoshoot), or if you’ve had spray tans before and want to level up from medium. Dark is the statement choice — still natural-looking when matched to the right skin type, but with more presence and richness.

Can You Go Darker Gradually?

If you’re unsure, the smartest approach is to start with medium and work your way up. A single session at 9% DHA will give you a clear picture of how your skin responds to spray tanning. If you love the results but want more depth next time, your artist can step you up to 12% for your next appointment.

This gradual approach is especially smart for first-timers. You’ll get to see how the tan develops, how it fades, and how your skin interacts with the DHA — all of which helps you make a more informed decision about going darker in the future.

The Bottom Line

There’s no universally “better” option between medium and dark. The right choice depends on your skin type, your undertones, the look you’re going for, and your comfort level. A skilled spray tan artist will assess all of these factors before recommending a solution — and that personalized approach is what separates a great spray tan from a generic one.

Whether you go medium or dark, the most important thing is that the shade complements your natural skin rather than competing with it. That’s the foundation of a spray tan that looks effortlessly natural.
