// dark becomes light) while keeping the original hues mostly intact, giving it a creepy, demonic look.
// Cranking up the contrast and saturation finalizes the signature heavy-meme aesthetic.

}The G-Major 741 Image Effect Generator applies a specific set of visual distortions to images, including color inversion, hue rotation, and adjustments to contrast and saturation. This tool is designed to create high-intensity, surreal, or stylized visual effects, making it useful for creators looking to produce meme-style content, experimental digital art, or dramatic visual transformations for social media.
