photoshop rgb question
 

i have a psd file currently open in photoshop that i am trying to change the color scheme of

now some of the layers seem to be 'locked' by that i mean they appear to have a style effect added to the which wont let me change the color of the original layer directly

does anyone know a way around this so that the base layer can be changed using a sliding rgb scale instead of having to turn off the blue and red hues to make it completely green?

i presume it must be possible somehow but atm i can only create a version in blue, green and red because of this and i need to have one version done in yellow and purple also lol

Hit me up on icq will see if I can help you out.
