Using Deep Navy ( #002D72 ) for the “Apply Now” button can be a good choice as well. It conveys professionalism and trustworthiness, which are important attributes for a job platform. However, since deep navy is a darker color, it may not stand out as well against lighter backgrounds compared to vibrant red or bright yellow.

To enhance visibility, consider the following tips:

• Use white text on the deep navy button for contrast.
• Add a hover effect that changes the button to a lighter shade or vibrant red to make it more interactive and noticeable.

Ultimately, the best choice depends on the overall design of your platform and how you want to convey your brand’s message. Would you like to explore more design options or perhaps discuss how to implement these colors effectively?
