Why do colors in my Flutter app differ from the Figma design?

Other Questions Figma

I’ve run into a problem with my Flutter project. The colors in my app don’t match exactly what I see in Figma or Adobe XD. Even though I’m using the same HEX codes, there’s a slight difference when I look at the app on my phone.

I’m wondering if this has something to do with color shades. Should I be using Material colors instead of HEX codes? Or is there another way to make sure the colors in my app match the design perfectly?

Here’s a quick example of what I’m dealing with:

import 'package:flutter/material.dart';

void main() {
  runApp(ColorComparisonApp());
}

class ColorComparisonApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: Row(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: [
              Container(
                width: 100,
                height: 100,
                color: Color(0xFF3A5795), // HEX code from Figma
              ),
              Container(
                width: 100,
                height: 100,
                color: Colors.blue[800], // Material color
              ),
            ],
          ),
        ),
      ),
    );
  }
}

Has anyone else faced this issue? Any tips would be really helpful!

I’ve encountered this issue before, and it can be frustrating. The color discrepancy you’re seeing is likely due to differences in color spaces and how devices interpret colors.

From my experience, using Material colors can help maintain consistency across different devices. However, if you need to match specific brand colors, you might want to consider creating custom color swatches.

One approach I’ve found effective is to use the ‘Color’ class in Flutter to define your colors, then adjust the opacity or brightness slightly until it matches what you see in Figma. Something like:

final Color myBlue = Color(0xFF3A5795).withOpacity(0.98);

Also, don’t forget to check your app on multiple devices and in different lighting conditions. Sometimes what looks perfect on one screen might appear slightly off on another.

Lastly, if precision is crucial, you might want to look into color management systems or consider using a color calibration tool for your development environment. It’s a bit advanced, but it can make a significant difference in color accuracy.

yeh, i’ve seen this 2. colors can be tricky in flutter. have u tried using the Color.fromRGBO() constructor? it lets u tweak the red, green, blue & opacity values separately. might help get closer to ur figma colors. also, different screens show colors differently, so perfect match is tough. maybe adjust til it looks good on most devices?

This issue is quite common in cross-platform development. From my experience, the color discrepancy often stems from differences in color gamut and display calibration between devices. While using Material colors can help with consistency, it might not always match your specific design requirements.

One approach I’ve found effective is to use a color management library like ‘flutter_colorpicker’ to fine-tune colors. This allows you to adjust hue, saturation, and brightness to match your design more closely. Additionally, consider implementing a color theme system in your app, which can help maintain consistency across different parts of your UI.

Remember that perfect color matching across all devices is challenging due to hardware variations. It’s often more practical to aim for close approximation rather than exact replication. Regular testing on multiple devices and gathering feedback from users can help you strike the right balance between design fidelity and real-world performance.
