It's been a LONG time since I tried practicing Pixel Art, but I'm sorta back to square one again, let's hope this sticks. I need advice regarding Color & Texture

wait do you change saturation when making color?, thats obrigatory, check color theory and shading

Sorry, I’m back, my migraines caused by my glasses; high grade has subsided

I was at Mr Mislav’s earlier lessons, most I can remember to do when changing stuff is change the Hue and Value, nothing about the Saturation, when it comes to shading or adding lighter and darker parts
