Examples

1. Hero Banner Text Readability

Web Designer
Background
A website hero image is too bright, making the white headline text difficult to read.
Problem
Need to darken the bottom of the image to provide contrast for the text.
How to Use
Upload the banner image, set the gradient type to linear, and use a black-to-transparent color scheme with a 0.6 opacity.
Example Config
gradientType: linear, startColor: #000000, endColor: #000000, opacity: 0.6, blendMode: over
Outcome
The image now has a subtle dark gradient at the bottom, ensuring the white text stands out clearly.

2. Stylized Social Media Post

Content Creator
Background
A collection of product photos needs a consistent, branded look for an Instagram campaign.
Problem
The photos have different lighting and need a unified color tone.
How to Use
Apply a radial gradient with brand colors using the 'Overlay' blend mode to all images.
Example Config
gradientType: radial, startColor: #FF5733, endColor: #33FF57, opacity: 0.3, blendMode: overlay
Outcome
All images now feature a consistent, professional color tint that aligns with the brand identity.
