As a Roblox developer, it is currently too hard to achieve a stylistic effects on images without the burden of uploading several versions of a given asset.
With monochrome icons, a grayscale effect can be partially achieved by turning the image color to black, and then setting the image transparency. However, this is not ideal for multi-colored images since the value component is lost.
Along with generally making images much more versatile, there are plenty of use cases for a feature like this
- An ‘unlocking’ effect for a tech tree or achievement menu
- A damage/injury effect
- Drop shadows/silhouettes for icons (with accurate transparency)
Optimal implementation would be a saturation slider, but a grayscale checkbox would also be welcome.
