在色彩相關的製造與設計產業中，從業人員經常需要利用工具調製特定顏色，除了使用實體色票、檢色儀器外，與裝置相關(device dependent)的數位色彩會採用RGB、HSB、CMYK、LAB等各種色彩空間(color spaces)調色介面來選擇或調配色彩。本研究問題為：數位調色介面的使用者在配製色彩時，其本身對於色彩空間的知識、或操作選色介面的經驗，是否會影響其配製色彩之正確率與效率?為了探討使用者利用一般軟體中的調色介面進行色彩配對(color matching)時，操作者本身對色彩空間的知識或技能對色彩配對表現的影響，本研究設計了以下實驗。本研究採用混合式實驗設計法、以滑桿操控的常見軟體調色介面作為實驗刺激、並讓受試者進行色彩配對作業。實驗中的組間變項是兩組受試者接受的兩種前置訓練，一組為陳述性知識(declarative knowledge)的教學，即對其講授調色介面中應用的色彩空間的原理；另一組偏向程序性知識(procedural knowledge)的練習，即提供不同色彩空間的調色介面供其熟悉操作、但不給與相關原理知識講授。組內變項為三種不同的色彩空間(RGB,HSB,LAB)的調色介面。兩組受試者完成學習之後，使用三種不同的調色介面進行12個色彩的色彩配對作業，研究者紀錄調色結果、完成時間、以及色彩配對過程當中的眼動資料。實驗結果顯示，實作組在進行色彩配對時所花的時間雖然比較長，可是準確性卻比教學組還要高。另外，受試者使用HSB色彩空間調色介面的準確性最高，即調色結果與目標色的平均色差(color difference)最小。
The color designers and color manufacturers often use multiple tools to specify or match the demanded colors. Such tools include color swatches of color order systems, colorimetric tools, or the device-dependent color spaces within the color matching user interfaces in common software applications. This study focuses on examine whether the background knowledge of color spaces affects the accuracy and efficiency of achieving color match with the given color matching user interfaces. The researcher conducted a color matching experiment with mixed experiment design. The between-subjects independent variable is the type of prior training, while the within-subjects independent variable is the type of color spaces. The participants were randomly assigned into one of two experiment groups with different prior training. One group of participants received instruction of the declarative knowledge about RGB, HSB, LAB color spaces; Another group of participants practiced to use the user interfaces of three color spaces to gain procedural knowledge about the spaces. The trained participants carried out the color matching task in which they adjust the sliding bars of the color matching user interfaces to match the given 12 target colors. The color matching user interfaces vary in three different color spaces, RGB, HSB, and LAB. The results show that the group with the practice as prior tainting has batter accuracy (lower color differences compared with the target colors) in color matching. Also, the relatively accurate color matching results are found in the condition of using color matching interface with HSB space.
