Which color scheme should be avoided for MHE designators?

When designing Material Handling Equipment (MHE) designators, it's crucial to ensure readability and visibility in various conditions. Pale colors are generally less effective because they can lack the brightness and clarity needed to be easily seen, especially in environments that may have poor lighting or distracting backgrounds.

Using pale colors might lead to issues with quick identification, which can be critical in a busy warehouse or manufacturing setting where safety and efficiency are paramount. Bright or vivid colors are often recommended as they enhance visibility and attract attention, while contrasting colors help differentiate between various elements. Harmonious colors can create a pleasant aesthetic but may not always offer the necessary visibility. Therefore, avoiding pale colors helps ensure that MHE designators are easily recognizable and effective for their intended purpose.
