Hi, Jade! I enjoy your artwork that so unique and experimental. Glad to meet you a green lover. :D
thank you SO MUCH for the kind words - i'm obsessed with your green layout & your "Degrading Beauty" series it's AWESOME!!! :D
thank you !! means a lot :D i'm working on uploading more art to the site over the next few weeks ^-^
Hiya ! I used the CSS "filter" property on each button individually to adjust the color of each. For dark one's I use "filter: invert(100%)" first which inverts the colors, making black turn into white for example. Then I used a mix of hue-rotate(), saturate(), brightness(), and opacity() on an individual basis to adjust it further. Feel free to right click > inspect my page and you'll see all code for yourself :)
then if you also want to remove the filter when you hover the mouse on the buttons, like I did, add a section to your CSS with a ":hover" event and use "filter: none !important;", this will turn off the filters ! For example my code looks like :#buttonmarquee:hover img { filter: none !important; }
hey :D! glad to meet another jerma fan :))!!
