Text in upper layer is not same.

(Problem)
My upper layer's paragraph are not same blue color.
(Situatuin)
Since my bottom layer is a gray gradient fill, the blue colors of upper layer's paragraphs are not same across the texts. Texts in upper layer are more bright blue than bottom one since the beneath layer has more dark gray colors at the lower part.
I made sure that the upper layer' blending is normal and its opacity is 100%. (Help)
I want the paragraph has same blue color looks, no matter how the bootom layer is shaped.

Thanks again

A colors appearance can be affecte by it's surrounding shades. If your text layer on the bottom is surrounded by light gray, and your text layer on top is surrounded by a darker shade, they may appear different.
