Summary
HEAT is a set of 14 heat-map gradient styles for Adobe Photoshop, supplied as a PSD file for $20.00. It produces thermal and duotone visual effects by mapping the brightness values already in your image to a colored gradient instead of to gray. The workflow is deliberately short: open the PSD, replace the provided photo with your own, and choose the gradient map style you like. It is an instant digital download.
What Is HEAT — Photoshop Gradient Maps?
HEAT — Photoshop Gradient Maps is a styles pack, not a plugin and not a filter. Everything you buy lives inside one PSD file that opens in Adobe Photoshop. Inside that file are 14 heat-map gradient styles — the thermal ramps and duotone ramps that do the actual color work — arranged so you can audition them against your own image.
- What's included — 14 heat-map gradient styles for Adobe Photoshop.
- Format — a PSD file. No installer, no extension panel, no preferences to reset.
- Compatibility — Adobe Photoshop.
- Look — thermal and duotone visual effects.
- Price — $20.00, instant digital download.
That PSD-based approach matters. Because the pack ships as a working document rather than as a set of loose assets you have to import, the styles arrive already wired to a photo. You are not building the effect from scratch and hoping you stacked it correctly — you are dropping your image into a file where the stack already exists.
What a Gradient Map Actually Does
A gradient map is one of Photoshop's adjustment types. It reads the luminance of every pixel in your image — how bright or dark it is — and replaces that value with a color sampled from a gradient. Pure black in the photo takes the color at the far left of the gradient. Pure white takes the color at the far right. Everything in between is distributed across the ramp.
Two consequences follow, and both are why gradient maps are worth understanding rather than just clicking:
- Your original colors are discarded — a gradient map does not shift hues, it replaces them. A red shirt and a blue shirt of the same brightness come out the same color. That is the point, not a bug.
- Your contrast structure survives — the tonal relationships in the photo, the thing that makes a face read as a face, stay intact. You are recoloring the image without flattening its depth.
This is what separates a gradient map from a color overlay or a photo filter. An overlay tints everything uniformly. A gradient map assigns different colors to different tonal zones, which is exactly how a thermal camera renders a scene.
Why Thermal and Duotone Looks Work
Thermal imagery is legible for a reason. In a heat map, the ramp runs through a predictable emotional order — deep blues and purples in the cold shadows, magenta and red through the midtones, orange and white where the subject is hottest. Your eye reads that ramp as temperature and as focus at the same time. The brightest, warmest part of the frame is where the subject is, and everything else recedes.
Duotone works on the same principle with a smaller vocabulary. Two colors, one anchored in the shadows and one in the highlights, produce an image that is unmistakably graphic rather than photographic. It is why duotone survived the jump from offset printing into album covers, tour posters, editorial spreads and streaming thumbnails — it reads at any size, including the 60-pixel square on a phone.
Practical places these looks earn their keep:
- Cover art and single artwork — thermal ramps stay readable when a platform shrinks your image to a thumbnail.
- Merch and poster work — reduced palettes separate cleanly and behave well in print.
- Video thumbnails and title cards — a duotone frame sits apart from the sea of untouched screenshots around it.
- Photo series with mismatched sources — running everything through one gradient ramp unifies shots taken on different cameras in different light.
- Social and campaign assets — one ramp applied across a set is an instant, cheap visual identity.
How You Actually Use It
The workflow HEAT is built around has three steps. Open the PSD in Adobe Photoshop. Replace the provided photo with your own. Choose the gradient map style you like from the 14 included.
A few notes that will make those three steps go better:
- Feed it contrast — a gradient map is only as interesting as the tonal range underneath it. A flat, low-contrast source produces a flat, low-contrast result in a new palette.
- Watch your subject's placement on the ramp — if the face lands in the same tonal band as the background, the two will take the same color and merge. Adjusting the brightness of the source before the gradient map fixes this faster than fighting the gradient itself.
- Try more than one — 14 styles means auditioning is cheap. The ramp that looks best on a bright outdoor shot is rarely the one that looks best on a low-key studio portrait.
If you want the click-by-click version — where the adjustment layers sit, which blend modes to use, how to clip and how to export — that is covered in the companion post on the Photoshop workflow.
Gradient Maps Compared to Other Color Tools
| Tool | What it does to color | Best for |
|---|---|---|
| Gradient Map | Replaces color entirely, mapping luminance to a ramp | Thermal, duotone, graphic recoloring |
| Hue/Saturation | Shifts existing hues | Correcting or nudging real color |
| Color Balance | Pushes tints into shadows, midtones, highlights | Subtle grading that keeps the photo photographic |
| Solid color overlay | Tints every pixel the same | Flat washes, not tonal separation |
If you work in video as well as stills, the closest relative to a gradient map in an editing timeline is a lookup table — a different mechanism, but the same idea of handing off your color decisions to a reusable preset. Our explainer on what a LUT is covers that side of the workflow.
What Pairs With HEAT
Gradient maps handle the image. They do not handle the type, and a thermal cover with default type on it looks unfinished. Pairing a reduced, high-contrast palette with display type that has some weight to it is usually the difference between a look and a finished piece — the MoonBear fonts collection is the place to start on that half of the layout.
Conclusion
Gradient maps are one of the highest-leverage color tools in Photoshop precisely because they throw away your original color and keep your original contrast. HEAT packages that idea as 14 ready-made thermal and duotone ramps inside a single PSD, so the setup work is already done and your job is to bring a photo and make a choice. At $20.00 as an instant download, it is a small pack that changes what a stack of ordinary photos can look like. You can pick it up at HEAT — Photoshop Gradient Maps.
FAQ
Q: What exactly do I get when I buy HEAT?
A: A PSD file containing 14 heat-map gradient styles for Adobe Photoshop, delivered as an instant digital download.
Q: How much does HEAT cost?
A: $20.00.
Q: Do I need anything besides Photoshop?
A: No. HEAT is compatible with Adobe Photoshop and arrives as a PSD, so there is nothing to install beyond opening the file.
Q: Will a gradient map keep my photo's original colors?
A: No, and that is intentional. A gradient map replaces color based on brightness. Your contrast and detail stay, your original hues do not.
Q: Can I use it on any photo?
A: You replace the provided photo with your own. Images with a clear range from shadow to highlight respond best, since the gradient has more tonal range to spread across.
Q: Is it a plugin or an action?
A: Neither. It is a PSD file with gradient map styles built into it.
