Hi,
For detection of specific colors, color-based segmentation using K-Means Clustering might help. Please refer the documentation link below for more information regarding this technique:
The provieded example shows how to segment colors in an automated fashion using the L*a*b color space and K-means clustering.
You can then perform a replacement operation to delete these lines and replace them with new pixel values.
