The so-called illustrator effect in the upper part is the pure vector deformation effect. Except for "dot matrix", all the effects are to deform vector objects through mathematical operations and then generate new vector objects.

The so-called photoshop effect in the second half is actually some popular effects transplanted from photoshop. All these effects use pixel effects in photoshop on objects. Of course, the generated effect is mostly composed of pixels. If these pixels are calculated and generated on the basis of vector objects, the objects will be simulated and rasterized for further operation, which often leads to the phenomenon that the original objects become pixels.

These effects can be applied to most objects in AI, not specifically whether they are vectors, but whether they are "gray" depends on whether they can operate normally and get results.

In AI, except for a few special effects such as rasterization, most effects can be released to restore objects. These effects can be found in the appearance panel, and can be revoked, copied and modified to "appearance" unless it is "extended appearance". Therefore, the "appearance effect" only represents whether it can be reversed by AI.
