How to Change Color Balance in PSD Photos with Aspose.PSD for .NET

Color balance correction fixes color casts, unifies mood, and creates consistent branding across large photo sets. With Aspose.PSD for .NET, you can automate this vital step for any number of PSDs.

Real-World Problem

Manual color correction isn’t scalable for modern marketing, publishing, or ecommerce teams. Consistency and speed require automation.

Solution Overview

Add and edit a Color Balance Adjustment Layer programmatically to set precise color shifts in shadows, midtones, and highlights for perfect results.

Prerequisites

  1. Visual Studio 2019 or later
  2. .NET 6.0 or later (or .NET Framework 4.6.2+)
  3. Aspose.PSD for .NET from NuGet
  4. PSD file(s) for enhancement
PM> Install-Package Aspose.PSD

Step-by-Step Implementation

Step 1: Load the PSD File 

using Aspose.PSD;
using Aspose.PSD.FileFormats.Psd;

string inputFile = "./input/photo.psd";
string outputFile = "./output/photo_colorbalance.psd";

var loadOptions = new PsdLoadOptions() { LoadEffectsResource = true };
PsdImage psdImage = (PsdImage)Image.Load(inputFile, loadOptions);

Step 2: Add a Color Balance Adjustment Layer 

var colorBalance = psdImage.AddColorBalanceAdjustmentLayer();

Step 3: Set Channel Balance Values 

// Tune the color cast in shadows, midtones, highlights
colorBalance.ShadowsYellowBlueBalance = 30;     // -100 (yellow) to 100 (blue)
colorBalance.MidtonesMagentaGreenBalance = 18;  // -100 (magenta) to 100 (green)
colorBalance.HighlightsCyanRedBalance = -15;    // -100 (cyan) to 100 (red)

Step 4: Save the Color-Balanced PSD 

psdImage.Save(outputFile);
psdImage.Dispose();

Use Cases and Applications

Common Challenges and Solutions

No effect on photo: Check adjustment layer order and channel settings.

Best Practices

  • Preview output in Photoshop for best results
  • Script for all PSDs in a folder for speed
