Problem Using the Magic Wand on Blended Shapes

[Ken5D91]

Hello Everyone, I'm very New at PhotoShop and needing to understand if this is possible. I need to create a "Spot Color" I have done this with plain colors without problems but now I have a Blended Colour that doesn't automatically get selected completely. I have attached the Image so if someone can explain to me how I can select the whole shapes and not incompleted sections,  the "Magic Wand Tool" just wants to create an outline around the same color and not all the Shades. Thanks in Advance

You can increase Tolerance for Magic Wand tool in the Options bar what will increase what is selected by selecting and similar colors, not only same or very similar. I think your task is dificult to accomplish using Magic Wand when it comes to selection, you may need to use some other technigue which involves other commands and perhaps channels or advanced blending options.
