@PKief The new Angular icon does not support Material colors. I’d love to get your suggestion on this—should we keep this gradient color exclusively for the Angular icon, or should we adjust it to align with the existing Material color scheme? Let me know your thoughts!

[PKief]

@JeevanMahesha thank you for the proposal. I can understand the idea and the will to make the icon as close to the original logo as possible. However, we're choosing our colors only from the Material Design color palette. The reason for that is that it gives all icons a very good contrast to other icons and makes the Material Icon Theme to that what it is: a good looking icon set with the touch of Material Design. Once we move away from that icons won't have that good contrast anymore and we're going away from the Material Design.

That's why I'd like to stick with plain Material Design colors and avoid adding gradients to icons if not absolutely necessary.

Hi @PKief,

Thanks for the detailed feedback! I completely understand the importance of maintaining consistency with the Material Design color palette. Since the gradient doesn’t align with the design principles for this icon set, I’ll go ahead and close this PR.

I appreciate your insights, and I’ll make sure to adhere to the Material Design guidelines in future contributions. Looking forward to collaborating again!
