Need more yellow color on the Top Plate

[paribartann]

Hi, I am trying to detect Husky via it's yellow color using UAVs. However, due to limited yellow shade present in the now-present husky, UAV is not being able to detect the color easily. I tried editing the .xacro and .urdf files, but not being able to obtain the yellow-shade. Would you mind letting me know where I can make those changes to add more yellow color in the Husky.
Thank you.
