Turn Your Phone Screen into a Professional Colored Light
Use your smartphone as a colored gel to add a creative edge to your headshot. This guide shows you how to set it up, control the color, and avoid common mistakes for a standout result.
Gather Your Gear: Phone, Tripod, and a Dark Room
You need three things. Your smartphone, a small tripod, and a dark room. That last one is non-negotiable. I once tried this in a living room with afternoon sun peeking through the blinds, and the colored glow from the phone screen vanished completely—it was a waste of twenty minutes. Total darkness lets you control every photon.
Forget the selfie stick. A cheap, flexible tripod you can clamp to a chair or set on a table is perfect. It costs about fifteen dollars. This holds your light source perfectly still, which is the entire point. Your second phone, the one displaying the color, is now a studio light, not a communication device.
What color should you display? A solid, bright screen. Open a blank document in your notes app and maximize it, or use a pure color background. This is your gel, your filter, your mood. We’ll pick the specific hue in a minute. First, let's place it.
Position Your Screen for a Subtle, Professional Glow
Here’s the secret: the screen is not a main light. It’s an accent. Place it too close to your face and you’ll look like you’re in a neon sci-fi movie. The goal is a gentle wash of color on one side of your face or shoulders, suggesting creativity and intentionality.
Set your “light phone” on the tripod. Position it about three feet away from you and slightly to one side. Now, angle it. Don’t point it directly at your cheek. Instead, aim it so the edge of the glow just kisses your jawline or the side of your neck. I watched a client adjust this for five minutes, shifting the phone millimeter by millimeter until the blue light traced the curve of her shoulder without hitting the wall behind her—that’s the precision you want.
Turn your main light on. This is your existing room lamp, a window (if it’s daytime and you’ve blacked out the rest of the room), or a simple ring light. The colored screen is now playing a supporting role, adding a sophisticated tint to the shadows your key light creates.
Choosing the Right Color for Your Industry
Not all colors send the same message. A vibrant magenta might be perfect for a music producer but disastrous for an accountant. Your color is a silent partner in your professional story.
Use these as starting points:
- Deep Blue (#003366 or similar): The universal choice for tech, finance, law, and healthcare. It reads as trustworthy, stable, and intelligent.
- Teal or Seafoam Green: Ideal for wellness coaches, therapists, educators, and environmental fields. It feels calm, approachable, and growth-oriented.
- Warm Amber or Burnt Orange: Perfect for creatives—artists, writers, designers, and entrepreneurs. It suggests energy, warmth, and original thinking.
- Soft Lavender: Great for beauty, lifestyle, and coaching industries. It implies innovation, intuition, and a gentle modern touch.
Avoid pure red, bright green, or stark white. They are notoriously unflattering on skin and feel harsh. Stick with muted, sophisticated tones. Pull up a color picker on your phone and choose a shade with some gray or depth to it.
The One Mistake That Ruins the Effect: Spill Light
What’s the fastest way to make this look amateur? Spill light. This is when the colored glow from your phone screen bleeds onto your background or the front of your shirt, creating a messy, unintended blob of color.
How do you stop it? You block it. Use a piece of black cardboard or a book wrapped in a black t-shirt as a “flag.” Place it between the phone screen and the area you don’t want colored. Is the light hitting the wall behind you? Flag it. Is it coloring your collar? Flag it. I keep a stack of black foam boards in my studio for this exact reason; on a shoot for a venture capitalist who wanted a blue accent, we used his own hardcover biography to block the spill from his white shirt.
Check your camera’s live view. Look for any stray color. Your colored light should have a clean, defined edge where you want it, and be completely absent where you don’t.
Uploading to Portraze for a Polished Final Image
You’ve shot a great raw image with a custom colored glow. Now, how do you ensure it looks professional and cohesive? The colored light might look a bit raw or uneven straight out of your phone’s camera. This is where final polishing comes in.
Upload your best shot. The platform’s tools can subtly balance the overall color temperature so your skin looks natural next to that blue or amber glow. You can adjust contrast to make the accent pop just a bit more, or subtly soften any harsh edges on the colored light. Think of it as the final step in a studio process: the retoucher’s pass to make everything seamless.
Why not just use a filter? Because filters apply color globally, washing over your entire image and often making skin look sickly. Your method places light physically in space, creating realistic shadows and highlights that editing software can then refine, not replace.
The practical takeaway is this: professional lighting is about control, not expense. By treating your phone screen as a precise, positionable gel, you’ve added a layer of intentional craft to your portrait that viewers will feel, even if they can’t name it. Now go flag that spill light.
