• 呼叫: import fullseye as fs; fs.ledger.color_correction_matrix(rgb, ccm, normalize_rows=True)(要直接呼叫實作,import gfx2d; gfx2d.color_correction_matrix(rgb, ccm, normalize_rows=True);從台帳取用則 opsgfx2d.get("color_correction_matrix"))
逐像素套用 3x3 色彩校正矩陣(預設行正規化為 1,白保持白)。

The CCM maps the sensor's spectral response onto the display primaries. With
*normalize_rows* (default) every row is divided by its sum so that **white
stays white** (`[1, 1, 1] -> [1, 1, 1]`) — the constraint most calibration
procedures impose; pass `False` to apply the matrix as given.
Ground truth: the identity matrix is the exact identity; a normalised matrix
maps every grey `[v, v, v]` to itself to 1e-15.
Raises `ValueError`: *ccm* is not a finite 3x3, or a row sums to 0
when normalising.
